I get that all the time from my boss (old-timer). He will ask me all these questions about new cars, after I answer his question he continues to tell me about how he already knew the answer with a " yeah I knew that" responce.

Sometimes I will get asked questions about something he obviously know nothing about and he will argue with me about it, its like dude, if you ask ME a question or MY advise you should respect my opinion. I have no problems toying around with idea's, but when he argues with me about how I am wrong...........grrr. Ohhh well......... what are you gonna do.
