Mostly lighthearted. 
Our boiler has decided to stop working and started leaking today when I have an important meeting at work tomorrow with a somewhat senior colleague. I'm grumpy about this because I hate having greasy hair at the best of times but least of all when I need to be feeling confident. My DH says he can't understand why it matters so much to me or why I need to be upset about not having a shower and invariably having to be the one who has to organise fixing it .
AIBU to think that the inability to wash one's hair is deserving of at least a mild grump, and that he's revealing a hitherto-unknown Neanderthal nature wrt personal hygiene?!
