My DS1 is 6. A couple of days ago a mum approached me and asked if DS1 could come to play with her DS the next day. I said yes, but when I mentioned it to DS1 he wasn't that keen to go, so I said 'go this time, and if you don't enjoy it you don't have to go again' and he went. He seemed to have quite a nice time in the end, but basically I don't think he really likes the other boy. He has lots of other friends and I don't think he feels the need to play with this boy.
The trouble is that I feel sorry for the boy (who I don't think has many friends). I am also embarrassed to ignore the social convention which is obviously that I should now ask the boy here to play, and then DS1 will probably get asked again etc etc. But is it fair to make DS1 play with someone he doesn't like, just because I am too weak to say to his mum 'actually, DS1 would rather not' - I honestly can't bear the thought of saying this to a perfectly nice woman!
What would you do?
