Heehee! My 17yo dd1 fired me recently for being 'an inadequate mother'. Apparently, she was disturbed that one week I'd made marmalade and cakes but nothing as interesting was forthcoming the following week (no, only a decent meal each evening etc!). Anyway, I've now been reinstated, as she needed a lift somewhere.
PS dd has a sign on her door - Ask a Teenager, while they still know everything.
