Do you keep pictures of people you used to know?

I sure do relate. I was cleaning up some old pictures from my family and when I went to school. Some of the family ones I don't even know who some of the people are. Since my parents are deceased, there isn't anyone to ask either. Don't know if some of them are relatives or not. The ones from when I was in school, shameful to say, I don't even remember some of the people's names anymore. The faces are familiar but that is about all. I even talked to my older brother about some of the family ones and he said, get rid of them and I agree. If we don't know who they are, no one else does either. I have kept the ones I remember for memory sake.
