LGBT peoples: how often does this happen?

I don't know if it's common or not, but if you sit down and compare one relationship to the next, I guess you can find this. Actually, you can find coincidences where you look for them, to be honest. Don't pay attention, because if you dwell on the past, you're going to miss the present. Enjoy what you have, be yourself, and if you have to look at the past for anything, make sure it's for a lesson learned.
