I took my son and his friend (both 13) on a day trip. My treat so they paid nothing which was fine.
His friend seemed to have a nice time. He was polite and said thank you before he headed home from our house.
His friend doesnt have a phone at the moment so everything was organised through me and his dad.
While organising his dad never said thank you at all. I thought he'd send a "friend had a great time. Thank you" text when friend got home. But nope.
I wouldnt expect that if my son and friend had organised it themselves obviously but am I unreasonable to think that because it was his dad and me, his dad should gave sent a quick thank you text?
YANBU - he should have sent a quick thank you text because you'd had to organise it directly with him
YABU - the friend said thank you, that is enough
Plus - how much is fish and chips these days?! I dont think I hid my surprise very well when she handed me the card machine!
