“A Charlie Brown Christmas” aired on TV last night and I got pulled in once again. Linus is my favorite of the “Peanuts” gang characters for being sweet, wise, and a good friend to Charlie Brown. In the special, he is the scene-stealer, literally taking the stage and standing in the spotlight to explain to Charlie Brown and their friends what Christmas is all about. He does this — as he does everything — with his beloved blue blanket. Couldn’t we all use a little blue blanket? For my grown-up self, I think a soft blue-as-the-sky scarf might just do the trick.
