Yep that's exactly how I meant it.
It's not a diagnosis as 'to be socially inept' is not a medical condition - it's a description and means, 'lacks skill' or 'clumsy'. Hardly the insult being made out.
@Renabrook to me going off the posts the woman does lack skill. It shows a lack of maturity if you're default is to blank someone/avoid eye contact etc because you're scared they may ask for another playdate for their child. It's the type of behaviour you might expect from a teenager not an adult who should have the manners, the understanding of their impact and the confidence to be able to remain friendly while also declining a social engagement she doesn't feel right for her.
Essentially it boils down to something quite simple - the OP has a child that really wants to play with another child outside of school. As parents we want to meet these requests from our child because we know how important they are to them. It can make you feel like you've failed your child for not being 'likeable enough' with another parent and in this case it's compounded by the other parent rejecting the OP even to the extent of not showing basic level kindness/politeness (exchanging chit chat/smiling/saying hello) while remaining friendly with other parents.
The OP has internalised all this as all her fault hence feeling sad.
There are many views and other perspectives some harder hitting than others but useful all the same for the OP to help view the situation differently and change her mindset.
But other views have been so unhelpful and have twisted the original post to such ridiculous proportions it's been simply a game to ignite argument, conflict and attack the OP. People do come to this forum for sport and it's very clear who those individuals are.
For me, it shows a lack of maturity if a person's default is to blank someone for something as banal as asking for a playdate - it suggests they don't have the social skills to navigate this situation in a more constructive less antagonistic/hurtful way.
So I stand by my perspective that the woman is being socially inept.
