This is a very jaded question. Regardless of what one says, you're gonna get crucified for it. That's why I have a small card that I pull out from my wallet and read it to her when she asks questions like this. The card reads:
I love you dearly but regardless of what answer I give you, I will be deemed a uncaring, insensitive, and/or an idiot. Therefore, I reserve the right to not answer this question or any other question regarding your looks, your appearance, your weight or any other member of the opposite sex. My reason for refusal is based on my desire NOT to sleep on the couch this evening. Did I mention that I DO love you?
