Hot surfaces

“Never ask a woman about other men. Either she'll tell you a lie, and you still won't know, or if she tells you the truth, you might not have wanted to hear it in the first place.”

This theory works regardless of gender — why touch a stove that you know is hot?

..and if it isn’t hot, why bother hearing a twisted answer that’ll leave you with more questions than before?

In many (if not most) cases, the best thing to say is nothing.
