I don't know, maybe I'm old-fashioned! I was always taught that it was very, very rude to stick out your tongue. It was the equivalent of telling someone to piss off.
We do it as a 'joke', with a grin, like when DH goes for seconds at dinner and me and DD make a comment about his wobbly belly, he'll stick his tongue out and laugh, but that's it. It's a joke.
Well DD (12) has a friend who does it all the time, to show she's annoyed. Like if she's here and asks for a biscuit and I say no because dinner will be soon, she sticks her tongue out at me.
I always say "Don't do that. It's rude." and she sing-songs "sor-ree". I'm good friends with her mum, but she also sticks her tongue out! I have mentioned it to her and she's sort of shrugged and ignored it - it's obviously just their way of showing irritation as a family.
Am I being stupidly, ridiculously over-sensitive about this? I mean, it's not a big, huge deal or anything, but it annoys the hell out of me.
Or maybe I'm PMSing and you should all send chocolate to the crazy lady.
