So do I. Who says it's supposed to be impossible, anyway? I remember at least half a dozen incidents that must have happened when I was two; by the time I turned three, we were living in an entirely different area:

-- My mother was explaining to me how birthdays worked. I must've been two (i.e., I was old enough to talk but we hadn't moved yet) and it's possible but not certain that it actually was my second birthday. I asked her if on the day a kid was born they did the cake thing too. She explained to me why not but I had some difficulty following her explanation.

-- The summer when I was two, we visited a community garden and someone presented me with an onion. I took it home, started taking it apart (naturally!), and quickly learned a lot about onions.

-- Around that same time, we went to visit my great grandmother. She had some very interesting-looking plants on her porch. I knew what you were supposed to do with flowers: you smelled them. I stuck my nose in one of her plants and pulled it out full of spines. I learned that plants like those were called "cactuses" but couldn't understand why anyone would want to keep them around.

-- We were visiting my extended family. My uncle was talking to somebody on the telephone. I knew just what to push to hang up a phone, and demonstrated. My uncle got mad.

-- During the same visit, I was running barefoot across the grass and stepped on a bee.

-- During that visit or one like it, someone showed me a cupboard full of honey they'd put up in wine bottles. We were going to have some ordinary yellow honey from a clear bottle but I wanted the kind from the green bottle because it looked so much more interesting.
