Ds is going on a field trip. I'm always really busy (aren't we all), partly because I help out with lots of community things and one is the school committee.
I spend a lot of money when funds don't come through to cover for stuff that's asked for or needed by teachers etc., it goes without saying that I have given a lot of my time at events.
School asks for money to pay for school trip. I mistakenly underpay by 20p.
I get a call from the school asking me to bring in the 20p.
AIBU to be a bit miffed.
