I don't know about you guys, but I have walls that jump right out in front of me. And I'm pretty sure the kids are laying trip wire and that's why I trip. I'm really not tripping over the carpet. 
My least favorite though is when I grab something out of the oven without an oven mitt. Then stand there for a few seconds thinking, Wow, that's hot! and wondering what to do about it. Then after I finally throw it down on top of the stove and run my hand under cold water I go right back and grab the damn thing again. Not that I've done it a few times or anything. 
It does make things interesting, though. My son told me something and I responded and he said, "I've told you this at least 5 times before, Mom." And I asked, 'Really? Tell me again.' And he does and then I say, "I know. You've already told me." pffffffffttttt He's so gullible.
Or my daughter today told me something I had told her. And I said, 'Really? Are you sure? Was I there?' Then she rolls her eyes and makes some comment about me not remembering anything and I told her she needs to work hard at school so she can become a neurologist and fix me. And then make lots of money, too, and buy me a pretty house. She then told me, "I'm not spending my money on YOU." Really then, I guess I'm going to have to rethink your guitar lessons. Rotten child.
