Why'd I say that?

I like to play devil's advocate, or is it that i like to argue? sometimes in a discussion, i'll take a position opposite of the one i really hold just so i can debate someone. i found myself doing this the other night. i let the other party (my mom) know that i was doing it, stating that, "i'm just playing devil's advocate, mostly because it's about the only thing i'm good at." well, turns out i'm good at saying really stupid shit too. my mom, who's becoming quite the movie buff, was telling us about a film they'd seen "The Story of the Weeping Camel". The story goes like this: camel has difficult labor giving birth to rare all-white colt, mother rejects colt, mongolian tribe summons musician, musician plays violin as part of ancient ritual, camel accepts offspring. After hearing the story, in a lame attempt to be funny, I say, "I should get a violin, so my mother will accept me." For a few seconds, there was an awkward silence. My brother, who actually is funny, said, "You'll have to take that one to your therapist." Later, I spoke with my mom privately and apologized for the stupid comment. I still feel horrible about it. This is a woman to whom I feel so close, only my wife is closer. This is a woman who has accepted me and all my baggage, when I didn't accept me and my baggage. Thanks for everything, I love you, Mom!
