"I don't like you." As an adult, have you ever said those words to someone?

Not about someone, but to somebody.

I’m limiting this question to incidents during adulthood. Little children often say, “I don’t like you” to peers and adults, mean little or nothing by it, and move along quickly.

I’m guessing that very few people say those words often, if at all. Most of us avoid being so blatant, and who needs the baggage from a confrontational declaration?
