Some people annoy the shit out of me.
People that are afraid to speak up, for instance.
Grow a pair!
It annoys me because they wait around for other people to say things and then reap the benefits, which they don't deserve.
But, they are lazy, and take the easy way out and therefore do not gain the strength and wisdom that I have gained by stating my opinions and beliefs.
In the end, they lose.
p.s. Unrelated but somewhat related side-note, Take responsibility for your actions and choices. Don't point the finger and blame others. This also goes along with being responsible for your personal belongings.
