Sometimes we have to forgive people for the lack of common sense.

Common sense is expensive nowadays, so not everyone can afford it.
Dear Mr. Know-It-All (a.k.a. "Intelligent"),

If being intelligent means being a jerk like you, then no thanks. Keep your 'smart'(-ass) to yourself.

Quick thinking and common sense are enough for me. Thank you.

With worst regards,

- Ms. Not-Impress (-At All)
