I've never been in the habit of upkeeping social connections, as most people either naturally drift away from me or I burn bridges with them. The single notable exception is my blood relatives, for self-evident reasons.
This tendency of mine applies not only to friendships, but also to any sort of activity that involves interacting with people. I tend to prefer completely abandoning someone whenever there's friction, or when I feel embarrassed or bored in their company.
The last time I burned bridges with a then-friend, the conclusion I took away from it was that I'm not suited for having friends, and it's better for others if I stay alone. It's a true observation, of course.
I was fifteen when that happened, and I've wondered how I should act if I somehow stumbled upon a new friendship after all that time.
The bottom line is that I've never really been honest in my dealings with other people, blood relatives excepted. I've never liked the concept of having other people change just so they'll be more agreeable to you.
