Sibling T.M.I.

My sister is one and a half years younger than I.  There's not a huge age difference between us, and the gap seems to get smaller with each passing year.  But it did seem somewhat bigger when I was 18 and she asked me one day, totally out of left field, what color "come" is.

Now, on most guys' list of "Questions That We Don't Want To Hear From Our Little Sisters", I imagine that one ranks fairly high, right up there with "Why do all the pages of the magazines under your mattress stick together?"  On the other hand, I did feel somewhat relieved that she still had to ask that question.

My second reaction was the fear of that question being followed by "How do you know?" if I answered her.

My third reaction was to wonder why the color mattered to her.  Was she worried about choosing underwear that wouldn't clash?

I honestly don't remembered how, or even if, I answered her.  Maybe my mind has intentionally suppressed the memory.  All I can say is ladies, girls, even though you may understandably regard big brother as the font of all wisdom, there are certain questions that are just too weird to answer.
