...We spoke our own language. And my favorite: Safe. Safe meant cool. It meant hello. It meant don’t worry about it. Once, when trying a certain trick on the beam(横杆), I fell onto the stones, damaging a nerve in my hand,and Toby came over, helping me up: Safe, man, Safe. A few minutes later,when I landed the trick,my friends beat their boards loud, shouting: “Safe! Safe! Safe!” And that’s what mattered-landing tricks, being a good skater.

What do the underlined words “Safe! Safe! Safe!” probably mean?

A．Be careful!

B．Well done!

C．No way!

D．Don’t worry!
