-You don't act polite when you don't want to? (i don't understand what they met, esp. with the double negative. Trick question?)

No, not a trick question, you may just be overwhelmed with all the questions lol.

Read the question this way: If you don't feel like acting polite to someone you don't.
yes/no, or true/false, or whatever they're having you answer. (Answer no/false/etc. if you want to say that you DO act polite even when you don't want to.)
