Do you enjoy a bridezilla drama, cheeky fuckers bumming free lifts? MIL thinks she's the mum of new baby not grandmum, what about the my mum treats my (infertile) sister's dog better than she treats my human child threads. Or how about the ones where a poster takes care of someone's else's kid and feeds them McD's, the mum then throws a hissy because her kid should have been fed quail eggs and smoked salmon!
I personally enjoy the car parking wars, especially when there's a diagram.
