Loved ones are not to be put aside, that's basic morality in my eyes. Thinking about friendship as in "it may always end, so why not end it now", is a way of thinking I do not like. At all.
I think what sniper is getting at is this. I only have one friend from school days that I still have regular contact with, he and I are truly best friends, my father refers to him as his third son. Our wives are best friends, our kids are too, heck even our dogs act like best buds, we are like one big family . However I have very limited contact with anyone else from school, some by my choice, others by theirs, but then again I wasn't very tight with a large group of people, I had some friends but I worked a full time job while I was in school too so I didn't have much time for a lot of social things. Sorry rambling, happens as you age lol. anyway I don't think real friends should be taken lightly but they will support you in whatever you do if they are true friends
