Which is why I find conversations like the one today at Target while I was looking at a t-shirt particularly distressing. I have no idea where it comes from.
Nathaniel: Mommy, that won't fit you.
Me: (bristling) What do you mean it won't fit me?! (Holding it up in front of me to show that it would most definitely fit me!)
Nathaniel: Yeah, but it's not long enough.
Me: What do you mean it's not long enough? It's a T-shirt.
Nathaniel: Girls shouldn't wear t-shirts. They should only wear skirts and dresses.
Me: ... Who told you THAT?!
Nathaniel: (gives a distressingly Gallic shrug--where did he learn THAT, too?!)
Me: Nathaniel, what am I wearing right now?
Nathaniel: (sweeping his eyes over my apparel and sizing up the pants and t-shirt with flip flops that is my every day look) Hm. Yeah, but you look like a boy when you dress like that.
There are days when I totally get those animal mothers who eat their young.
