DS1 (8yo) has been invited to a party at the cinema, to see a movie both he and DS2 (7yo) want to see. DS2 is not invited. DS2 is not bothered at not being invited, but gutted that his DB will see said movie while he doesn't (DS1 is the type to gloat, and DS2 is not the most resilient of characters - we are working on both points).
Would I be a bit of a CF/odd if I dispatch DS1 with the party group, then take DS2 off to a separate corner of the cinema auditorium and watch the movie with him? We'd be at the same screening (unfortunately only one screening per day) but not with the party IYSWIM.
Afterwards DS2 and I would make a swift exit, find somewhere for lunch (I know where the party group are going so will avoid that one!) and pick DS1 up at the appropriate time.
So in my head we're not infringing on the birthday child's party, but I just wanted to canvas opinions on the above and whether people would a) find me odd or b) want to be told in advance so they weren't surprised to see me hovering! DS2 truly does not want to join the party, he's just desperate for the cinema bit....
Please let me know your thoughts!
