goose bumps

the other day, I was kind of cold. Evening was descending and temperatures had dropped, and I shivered a bit. I noticed I had goose bumps. What are goose bumps, really? Are they not the skin's version of a race to find warmth, a la musical chairs? Your flesh is hightailing it to warmer territory, leaving the few cells that were slower than the others out in the cold. This continues until you are one large, shivering goose bump, when you, too, go in search of warmth because your brain is catching up to what your skin already knows. Baby, it's cold outside. (I say this because I got cold when it was a mere 74 degrees the other day.)
