I would agree if I was accused of being naïve and despite all of this real-world pessimism I fear there's an optimist trying to climb out. The odds, it seems, are against me. (See? There's that pessimism!)
My MBTI type is INTJ but beyond the robotic scowl, I go to great lengths to be sociable. I talk to strangers, tell jokes at awkward times, and will essentially bend over backwards to offer aid to anyone that appears to need a little help. I don't share drinks or take candy from strangers, though. Okay, I'll take it to be agreeable and avoid bruising egos but I won't eat it.
