Carol Platt Liebau notes that BO is a bit of a jerk. No, he's actually a monumental jerk.
Read it all and the references to a number of other stories which support the proposition.

He's selfish, vain, thin-skinned, and child-like in his need to brag about his imagined expertise at everything. His immaturity just jumps off the page.
