when were young, my sister and i used to push each other around in a laundrey basket. cute enough, right? well, one time she pushed my down a flight of stairs! we were getting close to the stairs and i was like, "turn around, we're getting close to the stairs, hey, turn around already, hey. hey. HEY! HEYYY! NO!" and down i went. the first, like, 4 steps i glided down easily--then i bumped and tipped and crashing down the steps, limbs askew. THAT is a painful sibling memory. whew!
