If people were able to hear my thoughts, I would want to crawl into a hole and die.
But, I'd probably be applauded for my acting skills, as the filter between my brain and my outward actions is incredible (especially at work). I could want to punch a customer in the face for whatever reason, and yet I'll still be cheery with them and try to strike up a conversation. If they knew what I was really thinking sometimes, I'd be long out of a job, haha.
