I crawled in from work with a horrible aching back tonight having had my period explode all over the back of my baby blue linen skirt - during a three-hour seminar, so I had to spend the whole time rigidly facing away from the class so no one could see 
Had been at work for 11.5 hours and was knackered.
DP had been at work as well but he had cleaned the kitchen already and said, 'Let me give you a massage' for my back and then put my dinner on to warm.
AIBU to feel deeply ashamed that I have ever resented finding his shaving hairs in the sink or ever shouted at him for not taking his fucking muddy hiking boots over before tramping all over the house with them?
