Help yourself. Feel free to expand on it as well, because the analogy holds true in many ways. You can also go into some of the inner lessons of it as well, such as:
1) They make look and sound sane and reasonable, but there are a lot of nuts pretending to be normal people. When they start ranting about whatever, think of the “public poopers.”
2) Some people even define their entire lives around their unimpressive quirk. They insist that everything that happens to them, good, or mostly bad, is because of their deviation, not for its real reasons.
3) They are “emotionally invested” in their weirdness, whatever it is, so they will ignore anything that says otherwise, no matter how sane or sensible. Debating them achieves little or nothing.
4) Deep down they think they want to be normal, but know they could never be happy with that, so they want abnormal to be redefined as normal.
It goes on and on.
Amazing! Just about says it all, thanks!
