I recently read about a study that said most people are happier if the majority of their friends have "less than them" because there are then no issues about "keeping up" or feelings of envy/jealousy to contend with. They also feel much happier about what they can afford/do, instead of a niggling feeling of being deprived.
This is a sensitive subject for me. DD is at a school where many of the children come from families with scary amounts of money. I went to one house to pick her up from a playdate, and thought "their sitting room is almost the size of our entire flat"! I am sad to admit that I have not asked this child back to ours for a playdate because we live so much more modestly.
We have a nice life, and we are fortunate enough to have some luxuries, but I must admit I don't like the feeling of having to watch cash flow when these other families don't. That being said, I have never felt any of these women being b*tchy, or superior.
The feeling of "inferiority" manifests itself in much less obvious ways - for instance, the mums group who wanted to have lunch out, and planned to go to Nobu! Or the evening we all went out for supper, and I realised to my horror that the evening had cost in the region of 200 pounds with shared cabfare to/from, babysitter, meal/wine, cab fare home for the babysitter (we got home after tubes stopped running)! I can't afford to do that, and it's not pleasant to always decline invitations. The current dilemma - a new friend from dd's school has moved to another country and has asked us to visit in September - I am unclear if the invite includes an offer of staying at their flat (I know they don't have a guest room). If not, we may have to decline, and I feel awkward even bringing it up.
I have some concern that dd's vision of "what the world is like" is likely to be highly unrealistic given how her contemporaries live. It's not the real world at all. That is one of the reasons I wonder if I should move her to a different school where we "fit in" better. I must say that I think the problem is mine because no one has made me feel self conscious, but it's not a nice feeling. And it's an issue for me.
