Is this in the medical books?

There's a phenomenon that I call "The 11yr old stupids" which basically means that sometimes 11 yr olds do something so astoundingly stupid and out of character it leaves you stunned, going "Wha?!? Bu...Wha? BUT.... WHAT?!?.............YOU ARE SMARTER THAN THIS!!!!!!"
lol
Victoria's most recent outbreak of this phenomenon happened when we were filling Brook's Father's Day cards. I'd left the room for a minute, and in that time, she'd put her name on the front of the envelope, like the card was for her. AND she'd gotten Ella and Colin to do it too.

HUH?

When I mentioned it, she gave me the look (that comes part and parcel with "The 11yr old stupids") you know, that blank look that either means "Nobody's home" or "I'm not stupid, YOU'RE STUPID", and said "I thought that's how you're supposed to do it. That way you know who gets what card."

HUH?

I then had to explain, very slowly, and in small words, that the cards say "HAPPY FATHER'S DAY" not "HAPPY 11 YR old Day"

ARGHBLARGHARGH!!!
