Friends that you had to let go.

After cutting ties with a couple of "friends" over the years, I've wondered if I was exhibiting some type of self-sabotage.
Was I trying to distance myself from people from some reason?
In a way, I guess but it wasn't to hurt my own interests. It was to preserve my sanity.
Some people are overly negative, abrasive, needy and corrosive.
The guys that only call when they need something are guys that I can do without.
The ones that don't understand that a conversation means that ALL PARTICIPANTS GET TO SPEAK are dudes that I won't miss.
