The doorbell rings. I answer it.
Julius the tree man: "Hi. Is your mom home?"
Me, after a couple seconds of silence: "Um, I am the mom."
Julius, the tree man: "Oh I am so sorry! You just look so young!"
It might have had something to do with the fact that I was still wearing my candy-cane pajama pants and a t-shirt when I answered the door, and I wasn't holding Amelia at the time. I guess I was dressed like a teenager who had slept in until mid-morning. Still though, I was flattered.
