I have been thinking about this more. I seem to have trouble making friends my own age. Most of the people I meet are older, often a good deal older, in their 60s (I am in my 30s). It's a combination of my interests and my schedule, I think. My retired friends are available to meet during the day, when I am. People my age are busy with families and careers.

It's starting to frustrate me, though. I just joined a social/volunteer group without researching it first and the next youngest person is in her 60s. Most of the others are in their 70s. I am just tired of socializing almost exclusively with people who are so much older.
