Out Of Sight... Out Of Mind?

Is the old addage really true? If its out of sight then it's really out of mind? I don't know but it seems like some people go by that. Especially when you have two people that are in long distance from each other. The only thing you can do is hope that is your friendship is strong enough to maintain through the rough patches, otherwise it may best to let go of the past and just remember the good times. Life is too short to dwell on things. I am happy with most of everything that is going on with my life and it would be cool to share that with close friends but maybe it just isn't mean't to be.. or just out of sight...out of mind...
