This one’s a witty one. If he asks you about what do you usually do when someone is annoying you, he’s actually collecting information for his future needs and trying to figure out whether he’s ever annoyed you.
So, when you give him an answer, he will process it in his head to see whether he’s ever annoyed you so far (because he really likes you).
Also, he will keep it in mind for future dates with you because he doesn’t want to fuck things up.
