I am not taking the piss itsmine (apologies I have been calling you itsme - that is genuine btw).
Glad you didn't deny digging at me and for the record, it is only you and lurked who are making the digs. I have not noticed anybody else doing it.
I do find school playgrounds hell on earth from previous experience and was just saying that some of the posts on here prove why I feel that way, along with personal experience!
Believe me- my DDs old primary had 600 pupils, I used to walk in the playground and walk by the "wall of death" as we used to call it as all eyes would be watching each mother. I remember almost trembling when my DD first started and having to walk past all the "established mums". I always saw a school playground as a way to make new friends .... I was soon wrong about that lol 
I too work but also know the school / class / friendship dynamics - just because I don't tread on eggshells around kids and parents over party invites does not make me a bad mother or person. But each to his own.
As I said, I did not come on here to argue, just to share my views but like anybody, when feeling attacked, I will retaliate. We both view things differently - so what? I can accept that but you clearly can't.
I will say again, each to his own, agree to disagree, there is no right or wrong view here, it's a free country, everybody is entitled to their own opinion view, end of.
