I don't tend to act the way I do in real life that I do online.. for the most part, anyway. People often point out that I have crude humour, but that I'm kind, too kind—I tend to be a pushover and I do lots of things and end up in lots of messes for helping people out that would've all been avoided if I just would've said "sorry, no". I would definitely say both are defining features of mine, more-so them mixing is the defining thing (they don't normally tend to go hand-in-hand at all).
That and my nose. x:
