Day 4: Comment to someone you haven't interacted with before or introduce yourself to someone you've interacted with and friend/follow them. It doesn't have to be anything complex - it can be feedback for a fanwork or discussing something you might have in common or even simply admiring their icon. The point is to reach out to someone you normally wouldn't and connect with them, even if it's only for the briefest moment.
I'm horrible at talking to people. x.x;; help. this challenge is the hardest so far.
