I try to avoid the local soccer/PTA mom's gossip sessions...my son has no interest in soccer so thankfully I only have to deal with them at the bus stop...
Invitations to most events, graduations, weddings, etc are usually dealt with by using my personal system...buy card, place money in card, mail. Most people that know me enough to invite me to these things would probably fall over dead if I happened to show up anyways.
I live in a little community of sorts and my yard is popular...roomy, level, full of plants, and I usually put in a big garden...so around mid-July I am usually wishing for 12ft high security fencing or winning the sweepstakes so that I can buy that island I've always wanted. So I guess you could say forced socialization, and my 8 year old are keeping me from becoming a recluse.
I've been trying different things to work on some of my sensory issues...my son wants a trampoline, I've heard that they help...I'll probably be in a full body cast come September...
I meditate...try to work on stress issues...because my ex still gives me a ton of it on occasion.

I am a soccer mom and have found taking my knitting or a book along gets people to stay away. I have tried to socialize in the past and found out that I got along better with the dads. Not a good scene! Women are jealous creatures apparently!
I found the trampoline keeps other kids away because the parents around here are very uptight and their children might be hurt so they are not allowed.
