Perplexing

I cannot understand a lifelong hockey fan/player who is also a lifelong resident of the UP of Michigan becoming a Penguin fan.  Do you just wake up one day and decide to jump on the bandwagon?  Do you want to cause your family members considerable amounts of pain?  Or are you just an utter asshole that likes to piss people off?  Knowing the person I'm talking about, I definitely think the reason is number three. The older I get, the more I don't understand people.
