My foot got caught on the stairs in school once and everything flew out of my pockets. My teacher tried to give me my stuff back and help me up but I just kind of sat there laughing and crying at the same time.
I have. And I've fallen down them a few times.
Plenty of times, I'm not that co-ordinated when it comes to foot placement. (I kick the floor a lot too)
Yes all the time
im not. Hope you weren't hurt too bad
