I took DS1 to the park this afternoon, and was pushing him on the swing when another little boy asked me to push him (I can't remember if he used "please").
I didn't think he was talking to me so I ignored him, but then I realised he was talking to me so when I had finished pushing DS1 I pushed him a few times.
Then I told him I had to go to look after DS1.
He did not even say thank-you, or show any sign of gratefulness or appreciation.
AIBU to have expected a "thank you" from him (he was about 7 I would guess, and I would have thought someone who has the guts to ask a perfect stranger something would have the "guts" to say thank you too...)
To make matters worse, later on DS1 was climbing across a bridge, and this boy just pushed past him. His parents were nowhere in sight...
