im a sahm and deal with school run/lunches/uniforms etc.
dd1 (4) came home with a letter saying we owed money for a school dinner in december, she takes a packed lunch every day which is eaten every day and as far as im aware has never had a school dinner, i asked her if she had eaten a dinner and she said no never (she is scared to stay dinners) so i put letter on fridge to take to office and query.
dp saw it on fridge and said whats this, why have they sent us this, we dont owe any money, they need to sort the facts before sending letters and then wrote on letter "not dd1, dd1 has NEVER had a dinner, try X" (a girl with similar name) whcih i was a bit
about as it was unnecessary imo.
anyway at lunchtime today he asked me if id been in office and i said no id forgetten but would deal with it.
tonight he asked had i been in office, i told him i had and they had taken a copy of the letter (which he had written on) and would look into it and said normally if a child forgets lunch they phone home first to check child can have a dinner so presume its the wrong name so its sorted.
dp then started saying, well why would they send us a letter when they are wrong, we are probably black listed now, what if dd needs a dinner one day and they dont give her one cos we are in debt, they should sort themselves out.
i told him its sorted and he was overreacting.
he said he needed to remind me as i had forgotten at lunchtime.
i said well its sorted now.
he said they shouldnt give a child a dinner if it isnt booked.
i said if dds forgot their lunch id prefer school feed them and ask for money after, why was he goig on?
he then said im rude and always have to be in charge and have the last word.
i told him to leave it as i was doing dinner.
he kept saying i had to have the last word.
i ended up shutting the door in his face and telling him to leave me alone and dd1 shouted "stop argueing" which was awful 
we dont normally argue but dp is stressed at work and had a friend in a bad situation at the moment and seems snappy.
i just felt he should have left me to deal with it and it wasnt worth a row.
aibu?
