I look at things differently I suppose Citizen of Legoland, to me the past is the past.
Sure, like you I can reminisce at times, but not grieve or reminisce too deeply, I can't change anything that's happened.
For instance, I'll reminisce about my best mate who was killed many, many years ago when he was 17. He's missed out on some fun, missed out on a family, all those things, but I don't grieve. When I'm back in May, I'll go to his grave and clean the leaves and crap off his granite marker, because nobody else does, but that's it.
A celebrity is a celebrity, that's all.
