I have changed

Has your idea of what makes a good friend changed as you’ve gotten older?

So this is what I was going to post:

Time has made me a cynic. There are no friends. I am useful to someone so they stay close. But that changes and they leave.

But:

I am a very hard person to get to know. Even harder to get close to. It is not friendship that has changed but me! I am not the type that has friends – simple!
