To cut a long story short I was asked to do a favour for a 12 year old by their parents. I was happy to do so. The 3 of them came round yesterday so I could do what I'd been asked to. The child did not say please or thank you, or even say hello, and the parents didn't prompt them to do so. I feel quite shocked and consider that to be rude, but I don't have children of my own so would welcome any views as to whether this is generally acceptable behaviour and I'm being pompous?
Btw, the favour was something the child really wanted to happen, not something they were being forced into.
I hope this isn't too evasive to get the point across but don't want to go into identifying detail!
TIA
