These two incidents happened in the exact same day and serve to illustrate how children's brains work really differently from ours, and how very weird parenting is.
I am driving Gwen to preschool, using the same route we use every time (two days of preschool every week = four times a week on this route). She suddenly says, "Hey! That's the park where we were in a race." I have no idea what she's talking about, so I try to get her to tell me more. After a few more little clues, it turns out she is remembering being in an egg race (you know, where you hold an egg on a spoon and try not to drop it) back in June of last year. She is entirely correct that this is, indeed, the same park.
I am quite impressed by her ability to recall this event, nine months later.
Gwen is using the bathroom at home. She has been potty trained for ~15 months, so I could estimate that she has used the bathroom approximately 2,281 times since then. I go into the bathroom to see how she is doing; she has stood up from the toilet but not flushed, which allows me to see the disappointing absence of a used wipe floating therein. "Did you remember to wipe?" I ask. "No! I forgot," she says. "How come you forget to wipe sometimes?" I ask. "Sometimes I just forget stuff like that," she responds.
Too busy reminiscing about egg races, I guess.
