Yet although officers will not disappear, it’s hard to imagine that working life will return to before-COVID-19 (新冠肺炎) ways. For more than a century workers have pushed themselves on-to crowded trains and buses, or suffered traffic jams, to get into the office, and back, five days a week. However, for the past one year they have not had to commute (上下班往返), and may enjoy it for a long time.

Employers, for their part, have supported expensive offices in city centers because they need to gather workers in one place. The rent is only part of the cost; there are cleaning, lightning, printers, catering and security on top. Needless to say, in the homeworking era these costs are cut down.

Another part of the homeworking era may be the disappearance of the five-day working week. Even before the COVID-19 many workers became used to taking phone calls or answering emails at the weekend. In the homeworking era, the dividing line between home and working life, a useful way of relieving stress, will be even harder to keep. It may be lost altogether.

What’s more, without the Monday-to-Friday commute, the weekend seems more nebulous, for employees may walk and take breaks freely, with only the company video calls unchanged.

Looking further out, the homeworking era may bring other changes. Some may decide to live in small towns where housing costs are lower, since they have no need to commute. Men will have fewer excuses to skip cleaning or childcare if they are not disappearing to the office.

In a sense, this is a return to normal: until the 19th century most people worked at or close to their homes. But social historians may still regard 2020 as the start of a new age.

We grow up with a mixed message: making mistakes is a necessary learning tool, but we should avoid them. And that’s a real shame. Because when we tell kids that learning is all about the results, we teach them that mistakes are something to be feared and avoided. We stifle (压制) their interest in experimenting because experimenting means you’re going to make a mess and fail. And that’s too big a risk.

Here’s a fascinating experiment that shows how children absorb what we say about effort vs. results. One of professor Carol Dweck’s experiments asked 400 5th graders in New York City schools to take an easy short test, on which almost all performed well. Half the children were praised for “being really smart”. The other half were complimented for “having worked really hard”. Then the students were asked to take a second test and given the option of either choosing one that was pretty simple and that they would do well on, or one that was more challenging, but on which they might make mistakes. Of those students praised for effort, 90 percent chose the harder test. Of those praised for being smart, the majority chose the easy test. Professor Dweck told me: “One thing I’ve learned is that kids are exquisitely (敏锐地) familiar to the real message, and the real message is ‘Be smart’. It’s not ‘We love it when you struggle or when you learn and make mistakes.’”

One way we can fix this is by understanding the concepts of “fixed mindsets” and “growth mindsets”. Those with fixed mindsets believe either we’re good at something — whether it’s math or music or baseball — or we’re not. When we have this fixed mindset, mistakes serve no purpose but to highlight failure. Those with growth mindsets are much more likely to be able to accept mistakes because they know that they’re part of learning. And it’s been shown that when students are taught about growth mindsets, their motivation to learn improves.

Uggs(雪地靴) are certainly ugly, or at least inelegant. The shapeless boots, pulled on in a hurry, can make anyone look like a slob（懒惰的人）, which has made them the target of disrespect. It hasn’t been hard to find someone strongly condemning them. “Ugg boots are no sexy,” The Independent declared in 2003, “unless you’re Mrs. Bigfoot on a lone mission across Antarctic to find Mr. Bigfoot. When wearing the boots, a writer of The Gloss complained, “There’s nothing to indicate that you don’t have square, horrible shoeboxes in place of human feet.” In 2015, one coffee shop on Brick Lane in east London ever banned ugg-wearers.

And yet, over the years, plenty of strange and unattractive shoes have met with the approval of the fashion establishment. The problem with uggs wasn’t that they were ugly; it’s that they were common.

But a funny thing happened on the way to fashion’s tomb: the universal ugg has not gone anywhere. Uggs have quietly stayed here since their best time. Once you start paying attention, you’ll be shocked to discover how many people are still wearing them. They are worn by mothers in town and in the country, by teenagers on Saturday shopping trip and by people in fashion.

Perhaps the secret of uggs’s unstoppable success is that, if there is a dividing line between public appeal and private style，it might be a pair of cozy boots. They are certainly comfortable, soft and warm, as if your feet were in the hugging of someone who really loves you. At $150 a pair, they are neither cheap nor entirely out of range. They are casual and indulgent(纵容的）.

Somehow uggs, the boots that so many people hate, have managed to challenge the cruel logic of the fashion cycle and carry on whether you approve of them or not.
