Easy Target?

I recently asked one of my close friends if I look like I am someone who is easy to get. He said I'm not easy to get but I am an easy target. When I asked why, he said it's because I exude this friendly, happy-go-lucky image and that I look like I'm game for almost anything.

With was has been happening in my life lately, I can't deny the fact that maybe I DO look like an easy target. It's frustrating because I get judged by people without them understanding who I really am. I may be a happy-go-lucky person but I know my limits. It's really starting to bother me.

Honestly, I don't want to change this trait but maybe, all this madness is indeed a sign that I should back off and lie low for now.
