Finding FRIENDS

How do we determine who our friends are, and why they are our friends?
I overheard the other day whilst waiting in a checkout line.
1st person: I don’t like John because he likes Margaret, and Margaret is a person that I don’t like.
2nd person: Well I don’t like Betty because she doesn't like Bill who likes Wilma.
1st person: Well, I like Fred because he doesn't like George, who likes Sally, and Sally likes me.
2nd person: I know what you mean, I like Sally because she likes you, but I don’t like John cause he likes Betty, who I heard doesn't really like Wilma, she only pretends she does.
1st person: Yeah, I know for sure that Margaret doesn't like John cause John was talking to Betty and Sally and Margaret doesn't like either of those two.
2nd person: It is so strange why people like some people and don’t like others, I like you Sue cause you really know how to choose good friends.
Anyone confused yet?
I am, Why must we not like someone because another person likes them, or why must we put pressure on people to like only who we like.
Why are we judged by the company we keep and not by our own actions?
If I say I like Joe and you don’t, then why must you not like me? Am I not allowed to pick and choose my own friends without being judged? Maybe my judgement is wrong but is that a reason not to like me?
I read somewhere where we only need 6 friends, why 6 I'm not sure, but according to what I read the mix of friends should be as follows. (The source of information, Herald Sun Newspaper, 11/11/12, Australia’s largest selling daily paper)
1/ The friend who is cooler than you.
2/ The friend who is up for anything.
3/ The friend who you aspire to be.
4/ The friend who doesn't know any of your other friends.
5/ The friend who is painfully honest.
6/ The friend who you have known longer than you have known yourself.
Now for a list of friends you should steer clear of.
1/ The friend who always cancel just before you’re supposed to meet.
2/ The friend who bitches to you about how unhappy they are in their current environment, but refuses to leave whether it be their marriage or job.
3/ The friend who always says “you look tired and worn out” with passive aggressive faux-concern.
4/ The friend who only contacts you when they need something.
5/ The friend who uses the calculator app on their phone to work out their share of the bill.
6/ The friend who always comes to you for advice but never listens to what you say.
7/ The friend who continually changes their mind quicker and more often than the weather.
This next friend should be dumped and never thought about again,
The friend that that tells you who you are allowed to be friends with who not to be friends with.

Friendship...is not something you learn in school. But if you haven't learned the meaning of friendship, you really haven't learned anything.
