Here's what I did with pictures of people from college or other stages of my life that I had difficulties with; I put the photos in envelopes and stuck them away in a photobox. It's been over 25 years for high school, and about 20 for college. If I still feel repulsed by these people, I throw away the *majority* of the photographs that don't have me in them (that would be most of them...I'm the Picture Taker) but I DO keep one or two of them because, like it or not, I DID have *some* good times with these people. I'll write those memories down, if I feel like it. They had some part in my development.
I had an experience of a lifetime overseas trip, and it turned out one of my friends was a narcisstic...I won't go there. So when I put together my scrapbook album, I left her in there, but *minimally*. She was part of the experience. I might hate her now, but it's been almost 20 years now, and now she's part of the ambience of that experience. There was good and bad. Who knows. Maybe I'll toss out those pages eventually. But for now...
There is one abusive ex from college that I did destroy all pictures of, however. Fortunately, he wasn't in many photos, and I can't find all my pictures from that time period.
