Relatively speaking

Today a stranger on the street told me after I parked my car: you are a good driver, rare are the ones who can park their cars with such easiness! I do hear this comment quite often and his words gave my ego a boost for a while after I walked away, then I got his point; he actually meant, rare are the women who can park their cars with such easiness!! Oh, he meant relatively speaking! I get it. When I was about to turn back he was gone. He got lucky for I wanted to hear him say: rare are the ones who punch this hard, of course, relatively speaking!
