My ds goes to an after school activity twice a week. This used be a group where all the parents are very nice, supportive non-competitive and just plain nice. It's a social setting I have felt very relaxed in and where the other mums I have met are all consistently kind and pleasant. I mentioned this activity to pushy mum whose ds is in the same class as ds and she instantly signed her ds up.
I can't really go into the ins and outs but this woman is the 'going over dead bodies' type of ambitious where her ds is concerned. She will be super nice to anyone who will help her achieve her goals and cold and dismissive to anyone who she sees as a completion or of no use to her furthering her ambitions for ds's.
I am unreasonably really disappointed that the club is not what it used to be with this pair of sharp elbows.
Please cheer me up with your own tales of pushy mums.
