I don't get some people! Had arranged a playdate for my DD (3) with neighbour's DD of same age as they get on really well at pre-school (according to teachers/observation etc!) - mentioned it to her and she claimed to have "forgotten" and was all funny about it ... hardly unusual, but why does it happen? Would normally simply avoid someone who doesn't want to play, and concentrate on my own friends (advice to DDs!) but this is hard as she is my neighbour, so unfortunately can't avoid as we walk same route to school ... Realise this sounds like a bit of a petty whinge, but my broader point is why are some other mums so plain old unfriendly? I do not want to be this woman's best friend, but our kids get on really well so why not make that connection? DP says think of her as difficult colleague.Have another really good neighbour/friend on same street - our older DDs friends, and we share pick-ups where poss, so know it's possible. Advice, please.
