To answer these questions fairly I would have to say that sometimes yes and sometimes no.
There are some who can realize who I really am and stay by my side, in good times and bad, and there are others with selective memory who only "pretend" during the time when my skills or knowledge can be of some use to them, but after they get what they need they forget who I am.
But honestly, I don't give a shit anymore haha. With me there are the people who know who I am and value me for it, I don't care about the rest!
