The other night while lying in bed and reading a story to William, he stopped me and said, "Sometimes you wear red pajamas, but sometimes you wear blue pajamas." I smiled and said, "Yes, I do. And the red ones are my favorite."
Will then went on to explain, "Sometimes Jack's favorite color is orange, and sometimes Jack's favorite color is blue, but my favorite color is always green."
For about a half an hour, William explored all the sometimes he could think of... and to his own delight, he sprinkled them with a little bit of always.
