[Spoilers Extended] Which book character do you hate/find annoying while reading but would actually sympathize/understand in a real life scenario?

Bowen Marsh is a character I found extremely annoying while reading ADWD because we read him from Jon's POV.

But once I finished reading and thought about it, I was kinda understanding of some of his actions.

Up until the point where he kills Jon, I was thinking this guy is making a lot of good points.

Jon really is letting a lot of enemies through to the other side (wildlings and the watch absolutely do hate each other and are enemies) and Marsh's questions about what they're going to feed the wildlings makes a lot of sense. Even after Jon gets the loan from the bank, he doesn't tell anything about it. Is Marsh supposed to read his mind?

Also, while as a reader I love the Stannis and Jon's relationship, Marsh does make relevant point that Jon is spending too much time with him and getting involved in politics by strategizing for Stannis.

Is there a character like this for you? Someone you find annoying while reading but can kinda understand when you think about it as a real life scenario.
