How Do We Know Each Other?

Swiped from kitanzi:

If I’m on your friends list, how do you know me? Even if it’s obvi­ous, even if you know me RL, please com­ment with a short blurb about how you know me.

Also, please give a tiny lit­tle bio­log­i­cal blurb about your­self. Tell me how old you are, where you’re from, a lit­tle rel­e­vant infor­ma­tion like that.
