There are nine years that separate me from my youngest sister, Amy. Just enough for her to be "in the know" for fashion, music, etc. She's saved my out-of-touch bacon on several occasions.
Today I had to call her to see if I could wear tan shoes with my black pants. I had seen it on TV. The combo got her stamp of approval. I felt a little dapper and a little uncomfortable (I'm very traditional, after all) at the same time. But since it got the Amy stamp of approval, I knew no one would laugh at me. (At least not that I know of.)
