My tickets are fading and it upsets me

I always keep my cinema tickets from every film I see at the cinema (I don't know why, I think just for....proof?) and I keep my 20 tickets from when I saw the movie version of Les Mis stashed in my copy of the novel.

Today when I was looking for a quote from the book I noticed that the ink on the tickets are fading, some of them are almost gone in fact and for some reason that kinda upset me.

I don't know why, I think it's just that if they disappear completely there will be no solid evidence that I saw the movie, and I think that sucks.

You can see on this picture that the words are barely there anymore, you can just about make it out if you look closely.
