Ref: Lesson 4 I Have a Bone to Pick with You!

Andrew and Rob are driving to Aunt Helen's place but are at each other's throat in the way.

According to Rob, Andrew is supposed to have the direction covered but does not hand the direction well for he's just a typical slacker who never gives a damp to anyone around him. He becomes a slacker lately, for example, he has to borrow Andrew's shirt for job interview. He twiddles his fingers and chats a lot with pretty girls at work. He does not lift a finger around the house to help out and not even pitch in with groceries.

However, Andrew points out that Rob just picks a bone on him and makes a mountain out of molehill. Andrew always tries to show everyone up, like a Mr. perfect. He has not changed since he was a goody goody as a kid. He is just acting like a child and needs to get off his high hourse.
