You can learn a lot sitting in a parking lot. The other day I was sitting in my car with my sons reading a book while my daughter finished grocery shopping. From time to time, I would look up and observe what was going on outside. One of those times I saw a huge, new, bright red, Cadillac SUV pull up in the parking spot beside me. Out of it stepped a well-dressed young woman in high heels. Her face was tight and determined and her eyes hidden behind sunglasses. I watched her as she headed for the store and wondered about her life.

A moment later a 30-year-old station wagon pulled up beside the SUV. It smelled of burning oil and probably didn’t have many months of life left in its engine. Out of it stepped a young mom with 4 little girls all under the age of 12. All were dressed in worn clothes. She gathered them together and they headed to the store laughing and talking all the way.

A while later I saw the Cadillac lady coming out, pushing a cart filled with a new television set. She threw it in the back and pulled out quickly, her eyes still hidden, her face still frowning. Fifteen minutes after her the station wagon mom emerged with her little girls. They had a week’s worth of groceries in their cart. After unloading it, the mom took out two pieces of cookies, broke both in half, and gave each girl a half of cookie. They smiled like it was the most priceless gift in the world. As they pulled out I thought about the two women. I clearly knew which one had the most money, but I wasn’t sure which one really had the most.

In this life there are many kinds of riches but the most valuable one of all is love. The truth is the one who loves the most: learns the most, lives the most, gives the most, and grows the most in this life. It is the real riches of this life.

You can use your smartphone to get pretty much anything delivered directly to your door almost immediately. The hardest part is the process of trying to work out if you should tip and if so, doing the quick math before you get to the door. And, you know well that you should tip about 15-20% at restaurants, but do the same rules apply to delivery drivers?

The co-founder of Grubhub, Matt Maloney, pretty much set the standard for tipping delivery people in a Facebook post. He’s a strong supporter of tipping, and Grubhub’s website suggests a $5 or a 20% tip. Maloney also said this number should go up if you order during, say, a snowstorm.

However, most other delivery services say on their websites that tipping is not required. Some services, like Door Dash, do suggest no tip on their checkout window. Many, like Amazon Prime Now, allow customers to change their tip amount after their delivery has been received to reflect the quality of service. These companies help customers save money but delivery drivers are upset. They deal with bad weather, heavy traffic, extreme tiredness, and more, all for a $1 tip. Many feel that if you’d tip your pizza boy or girl, you should tip your delivery driver.

The Emily Post Institute (EPI)’s official suggestion falls in line with Maloney’s: “10-15% of the bill, or $2-5 for pizza delivery depending on the size of the order and difficulty of delivery.”

Just like servers in a restaurant, delivery drivers almost always rely on your tips for their income. Tipping is a long-standing cultural tradition in America. So, until drones (无人机) can deliver hot dogs straight to your door, it’s best to tip the people riding through the city at all hours to bring you hot fresh food.

How do you kill your time on your way to work? Most of us stare at our cell phones, and refuse to make eye contact with others. We just read, chat with others online or play games online. Or maybe we' re using the time between stops to do our makeup, catch up on emails, or read a few chapters of a book. However, Dina Alfasi takes a very different approach.

Each day she has to travel hours on buses and trains to get to her engineering job at a hospital in Israel . Rather than look at her cell phone in silence, she uses one very special way to have connection with strangers. It is portraits of the people she meets on public transport every day that she is taking. The paintings catch those quiet and personal moments of people readying themselves for the day ahead. Some people lean their head against the window and go to sleep, some stare into space and have a daydream, and others sit quietly to read their documents or books. Each picture catches one tiny moment in people's lives, ripe with potential for your imagination. It is wonderful for her to look at someone's commute （上下班）and make up an entire story about the rest of their daily existence, from the father travelling with a baby to the woman welcoming a change.

“ What inspires me very much are the little moments that happen every day," Dina told My Modern Met. "My work is to tell stories through a single portrait, and it proves that all you need is just to look around and find those magic moments.”
