Another observation...
This happened on the way from picking chiya up from school. There's a kid in her class who really likes her and she likes him back, all innocent. So that day "R", the kid, had done a craft in his class and made a little dog out of something, chiya hadn't done anything so fancy, but she had done a craft as well.
Anyway, so we're on the way to the car now and there's another cute little first grader who says hi to "R", he says hi back. Chiya and he resume conversation. Diya, "so what have you named your dog?" R: "K" (the name of the other girl). Diya: "WHAT?" "K!!!" Poor kid backtracked so fast and said "sorry, it's Diya." and all was well....
