Yes, I know it hurts when friends leave. The way I try to look at it, though, is that I think of the blessing I got when I had that friend in my life. I think, for me, even though they might leave later and that will hurt, still deserve to have their friendship, even for a while. I can get lots of good things from that friendship, and it might last a little while, or I might get lucky and it might last a very long time. I don't know if I don't try, though.
