People with hiccups (including me).
The rest of my family dumping their shoes just inside the front door rather than placing them ON THE SHOE RACK OPPOSITE.
Sexism/misogyny including that caused by women pandering to men.
Cruelty to animals. Includes people getting pets with very little thought and rehoming a few months later because they don't really have the space/ time/ it's a pain when they go on holiday.
Small children in forward facing car seats much earlier than recommended. (Seen as an exciting milestone to do it as soon as possible ... thereby increasing said child's risk if serious injury and death - lovely. )
People who don't pull their weight at work then get tearful and offended when you point it out.
My kids moving my own personal chargers. I am happy for them to use them but LEAVE THEM WHERE THEY ARE. Same goes for use of other personal items. Husband borrows my hairbrush to do daughter's ponytail but doesn't put it back. Sometimes I've missed my train to work because I'm looking all over for it so I don't leave the house looking like Worzel Gummidge.
People who think their time is more important than yours.
When I've spent ages cleaning the kitchen or bathroom and one of the children desecrates it before I've had the pleasure of cooking in a clean orderly kitchen or having a lovely bath in a clean bathroom.
My husband's inability to budget and save money. We have semi- separate finances because of this but it means I end up paying for significant one off expenses like household renovations because I have savings and he doesn't.
My teenage son sticking a dripping coffee spoon in the sugar jar so when I come to make a cake I find the sugar all full of hard brown lumps.
Remote controls not left in correct/ logical place. My youngest has a habit of losing them down the side of the sofa, then collecting remotes from the other rooms until there are FOUR remotes left between the sofa cushions in the kids tv room.
