Everyone, in real life or not, has a few traits or behaviors that people find annoying. That's the way of life. Finn... it's just about everything all the time. He continually does and says the most ridiculously insensitive and conceited things, and gets that shocked and confused look on his face when people get upset. Like I said, I don't know why people like him as a character at this point. I am uncertain if we are supposed to or not.
