A couple of weeks ago we went a wedding (pics below). We stayed on a camp ground for the weekend. The weekend was an eye opening experience. I found that I was doing more with the people in the 55-65 age group than the wedding party, who was my age. They would go off to drink at the hotel and I was the baby sitter for the kids. They would go outside to talk, and I would be inside talking with the others.
Yesterday I went to a bachelorette party for my soon to be sister n law. Again I was talking to the three women in their 60's because all the other ladies didn't have kids and were single. They were almost all 29 and one was 34. Its strange to have all these people at the same age but different points in their lives. I had no desire to take shots of drinks. The older people were just hanging out and enjoying being there and the younger people were scoping the men. We were at a restaurant and I left as soon as I finished my dinner because I didn't want to go and party afterword.
I think it may be that I am married and have children. When you are settled in your grown-up life, there is a contentment that comes with life. I have always been an old soul. I also don't drink and drive.
