I Get Irritated By People

I think I get along with most people. But what irritates me are the people who can't stop asking for pics. I understand you need material for your extra-curricular activities. But I never agreed to be your source. When (not if) I say no, I mean no. I don't mean please ask over and over.
Three friendships on here lost due to my "don't make me say no twice" policy.
