I know someone who always seems to take the opposite stance, even when the situation is simple or casual. For example, if I say I like a brand, a show, or a place, she immediately starts explaining why she hates it and goes on about what is wrong with it. I am not trying to debate or prove anything. I am just sharing something I like.
It does not feel like a normal difference in opinion. It feels automatic, as if disagreeing is her default reaction. After a while it becomes draining and makes me avoid conversations with her.
Why do some people behave this way, and what is the healthiest way to handle or respond to someone who constantly contradicts what you say?
