*huuuuuuuuuuuuuuuuuuuuuuuuuuuuuugs* I know exactly what you mean. A few years ago I was in a history class, and they showed a film that included interviews with people who were all roughly of the same age and cultural background as my grandfolks and I started crying somewhere in the middle and had to excuse myself when it ended, because I couldn't get it under control. Sometimes things remind us of the good (or at any rate, in the case of my grandparents, the complicated and human and hurting and brave) so strongly that it pushes the grief back over us like a wave. Perfectly normal, but certainly very ouch.
