I don't see the point in keeping stuff like that when a relationship ends, I don't take any photos or anything like that either. I think it just gives time for people to dwell and I'd rather just move on with life.
China Doll's thrown away all mine because of the bogus sentiments in them and I've thrown away all hers because she never paid the postage on them, so it's just me and the Nigerians now plus a few amorous Russians seeking electronic assistance.
