I'm one of a small group of women (50's to 70's) who used to work together. We kept up afterwards. For the last few years I find I don't want to meet in a group any more. One at a time is fine, they are all nice people.
In the group meet-ups, I feel like an outsider, and would rather meet them as individuals, where it's one-to-one and more 'equal'. By this I mean that I feel I have nothing to share with the group as their lifestyles are so different from mine. One has a tick-off list of World Heritage Sites to visit, more than one house, and a collection of bottles of spirits from every distillery in the UK. Another has a large collection of £300-£400 handbags. One more spends months away visiting family all over the globe. They have all worked hard, married well and done all the right things: they deserve every penny they have.
For myself, I am getting by on my OAP and two work ones which add on another £300 p/m. I live in a Council House, rarely have holidays (except short ones in the UK), and haven't much in the way of savings. All of which is my own responsibility, and no-one else's. In fact, I think I'm pretty fortunate to be so well-off when others are homeless and starving. So please don't think I am sulking because I'm jealous: I'm content with my life, I just hate these catch-ups where three of the others are - frankly - bragging about their wealthy lifestyles.
I don't know if I am being envious / snobby / or just need to stop seeing them as a group. I get on fine with them one at a time, and one of them is a very good friend...
