True! I'll explain myself further:

My T is the sort of guy who can easily come across as a jerk because he jokes and doesn't always think through what he's saying. It's the kind of jerk that doesn't mean to be, and he's actually a really good guy.

My brother, on the other hand, is the opposite. He seems like a great guy, but he's a bonafide jerk and treats his friends like crap at the end of the day.

It's a difference between their actions and words. My T's actions are good, but the words he uses are sometimes a little daft - and his sense of humour can be questionable (but so can mine. I laughed a LOT when my friend told me what he did to her. It was terrible, but hilarious. I would have killed him if I'd been her!). My brother's words sound great, but they're empty and his actions are not good.
