Am I really so annoying?

Three things happened to me yesterday:

A friend told me that something I said to her was the meanest thing that anyone has ever said to her.

Another friend spitefully followed my advice in order to prove me wrong, and the advice turned out to be right. Things turned out legitimately great for her. And yet she was annoyed by her inability to prove me wrong.

A student told me that my suggestion for improving her essay was brilliant, but that it was probably just dumb luck on my part.

I clearly have a polarizing impact on people.
