TheTrewthHurts
First, it is from an old quote I heard first hand - If the truth doesn't hurt, it's not working. Second, I can use it as a way to explain both being better at something than you and not being better at something than you.
Examples:
You are better at "it" - The truth hurts you because it could be said that you have no life and all you do is spend your time on that thing.
I am better at "it" - The truth hurts you because I am better.
Yes, pretty weak. I know.
