DS2 (age 8) has been invited in a playdate with a classmate (B). B's Mum asked me in the playground and I accepted, thinking great, DS2 will love this, as it would be a change from the after school childcare arrangement. When I told DS2 of the invite he was emphatic that he did not want to go as he did not like B. (B seems to be having a pretty boisterous phase at the moment which is what is why DS2 does not want to go). They have never been particularly close, but the family seem lovely from what I know of them (playground chat) and I thought it would be nice to encourage this friendship. However, I feel that I should respect DS2s decision not to go.
So, how can I let decline this invite by causing the least offence? Shall I take the frank and honest approach by saying that DS2 does not want to play with the child at this time and that I hope they will be able to arrange something in the future, or should I play down the reasons to spare the feelings of B and his Mum? Advice welcome.
