Earlier this week, my 6 year old comes marching in to our living room at 9:30 (way past her bedtime) and announces that she wants her hair short. She's spent the last year growing her hair out as long as possible, so this was a bit of a surprise.
My wife and I told her to go to bed and that we'd talk to her about it the next day.
Apparently, she then promptly got her sissors and cut her own hair. She chopped off about 5 inches.
My wife didn't really notice at first - but then completely lost it when she realized what happened.
I find entire thing hysterical, and look forward to telling this story to relatives for years and years!
