I am not sure if this means that GAG is a mirror to me, but I did notice something. After reading a question, I sometimes need to stop and think about it for a while. While thinking I discover new things about myself. Like, I come up with a new way to solve some kind of problem simply by thinking deeply about it. And I was originally thinking so I could answer the question and help the person. It's kind of like teaching myself something new simply by thinking about a question someone asked.
I can be me, I do speak my mind on a regular basis but not about sexuality and stuff lol! So this is a way for me to be open about any and everything and try to help people too, which I love to help people, and get help sometimes too :) So in a sense it its like a mirror, it is more my perception of myself than in my regular life... People perceive me way different than this.
