I leave with my family for vacation tomorrow and I just found out we're going to be at the same resort with another family we know who are massive Michigan fans. They're good enough people, but the dad is obnoxious and he's your typical arrogant Michigan fan who thinks the program is angelic.

I've seen him once since The Game. He grinned and asked me how I was doing in a condescending way and I passive aggressively responded by telling my daughter (who was next to me) that 'cheaters never win'. He played it off but I could tell he was incensed. 

I don't want to spend my precious vacation time pissed off and having passive aggressive conversations with this guy. But I also want to make it clear that  Harbaugh is a dirty crook and that nothing they achieve is worth a damn.

Any thoughts or advice on how to deal with being stuck with a boastful, arrogant Michigan fan?
