Parks around here are very seasonal...so I am looking forward to getting out again with ds come March or so. We had some similar stuff last year, and I am not sure why it happened. Could have been $$. I live in my heavily mortgaged $90,000 house in a very economically diverse neighborhood--there is subsidized housing, places like ours, and $250,000+ homes all within just three blocks. The park where we play is surrounded by, literally, about 30 mansions--worth a lot. People live in them. They come to the park too.
Most are friendly and interact a lot. Dogs are allowed, and I think they help to warm it up among people.
Last summer, thougg, ds and I were playing on the swing, and there was a group of this time just 3 or 4 moms, and they made it very clear that they all know one another from CHURCH, where they are all active in that CHURCH, and then one got up to go, and they would see her at CHURCH...and, well, one knows by looking, I don't go to church.
But I stayed friendly, and asked a few Qs about the kiddos to keep it light, and ds tried to share his drink, and I think we made a friendly impression anyway.
What was the point?
I've had similar things at the library, but there I think it was more because I'm too fat. Not sure, but the fancy ladies were ignoring another fat woman, so it was probably that.
So now, I make a point of talking to Moms, and not judging them ahead of time. Remind me of this, come spring.
