I'm not a violent person, but when a guy asks me this, I want to cause him severe bodily harm. It's like how job interviewers ask you, "What's your worst quality?" This is a lousy question! I'm trying to put my best foot forward here. I'm wearing mascara. I turned my cell phone off. I shaved my legs. Enough with the interrogation, Sipowicz.
What could I possibly say in response to this?
"I'm single because I shanked the last guy who asked me this question."
"I'm single because I wanted to subject myself to lame questions that make me defensive before I've even finished my first drink."
"I'm single because I haven't met any guys who haven't asked me this fucktarded question that have lived to tell about it."
Guys, we love you, but PLEASE do not ask a girl this. It puts us on the spot. Ask about the time we went to Italy. Ask about what it was like when we went to Space Camp. Seriously, ask us ANYTHING except about why we're still single. Otherwise, we will stab you...with our eyes.
