I have. Coming into a dark apartment wearing sunglasses, hands full of miscellaneous junk, going up a practically pitch black staircase into a hall with all the doors closed. Recipe for disaster, it is.

My mother took pictures of me an my prom date on our stairs one year and i went up to get something, I fell up then she fell down trying to catch me. it was hilarious

Hell, question is, who hasn't?!

I've done that too many times to count!
Not only is it a huge surprise (especially when I'm running and skipping steps anyways) it hurts big time (especially when I'm skipping steps).

Tons of times. It's usually to do with the fact that I wear ridiculously long skirts and then forget to hold them high enough off the ground. Of course, sometimes I do it because my body likes to mess with me for the lulz.

Omgosh, I do ALL the time.
I did at school a while ago, and there were people behind me and they just laughed. -.-
And they were concrete stairs, so i grazed my knee.

I do that practically everyday LOL, so does my mom.

omg I hate that it happens to me all the time :<

All the time.

I want a lawyer.
