I wish I didnt miss a certain someone, too. But the reasons we miss them are the reasons to smile about it. We have good things to remember, and miss, and be glad happened even if they're over. That's what life is all about. Remembering the good times.
I also miss a particular person. I would very much like him out of my mind. One of the best pieces of advice I've been given is not to mistake grief for love. Missing or longing for a person is not necessarily a reflection on how much you loved them, it's a reflection of your own humanity.
