friends forever?

why is it that i let myself get upset about friendships that aren't really there? are they any better than acquaintances if all we do is hang out here and there? i know i've always known that if something happens i couldn't count on some people...i don't think any of them would be the first person i call if a tragedy would happen.....


why is it that the older i get, the less close close-friends become? does that even make any sense??
