I once got a jar of cherry-flavoured jelly beans from a friend as a congratulation gift. She was super thrilled about it, and explained that she'd seen that I always have a little jar of cherry-flavoured jelly beans on my desk, so obviously they were my favourite, and wasn't she clever for figuring it out?

I didn't have the heart to explain to her that the reason the jar had a buttload of cherry jelly beans in it isn't because I like them, but because I hate them and they're the only flavour out of the multipacks I buy that I won't eat.
