People drift in and out of one's life I guess, I'm old enough to have had it happen many times, and I generally move on quite well however that doesn't negate or eliminate the feelings we have when it happens right?
but cheer up, mate...
I'm not un-cheered at all actually, but it's probably difficult for you to know that considering you don't know the situation at all. That doesn't mean I don't feel things though, that the loss doesn't effect me. I have a heart after all, contrary to what some believe.
