Went to a birthday party today for my child in reception. It was a whole class party in softplay with other parties happening at the same time. There was a table set up for the parents which I sat at and tried to speak to a few parents. I know most to see from drop off and I tried to be friendly and chatty. Twice a parent I had been talking to for a while got up to "get a coffee" and then moved to a separate table with one or two other parents to obviously have their own conversation. I think some of these parents know each other better through having older kids at the school but it just seems so b*tchy to me and immature. Im now replaying all the conversations I had and worry i overshared or said something embarrassing for this to happen twice at one party. Im keen to be friendly with these Mums so maybe that came across too much and put them off? Just feels strange to me that other parents wouldn't want to be friendly at a kids birthday party. Is it me? Or is this just how some grown women behave?
