One person

You know how through school many people have that one best friend?
I figured out pretty early on that I didn't have just that one person. Instead, I liked having several really close friends, the ones that I couldn't bestow the title of 'best friend' upon, because the others would be disappointed.
I've quite liked the idea of having several, and grown into the notion that this is totally sustainable :) You know, good friends for different things. It may well be hard to have that one person understand absolutely everything (even though they may try!) unless they're pretty much the same as you - and that would be weird....!

On the flipside, what happens when you're in a place where you need to talk to somebody and you can't quite put your finger on the right person to listen? That's the tricky part...
as well as when it's commonly assumed that just because you're an old-hand at the stuff around here doesn't mean you don't have moments of weakness
