Just in case

Yesterday morning, around 4:00am, Annie woke up, thinking her nose might be bleeding. (She gets a nose bleed kind of often, about once every month or two, and usually during the night.) Gratefully it wasn't a nose bleed. After we made sure that was the case, I gave her a hug and wished her a happy birthday and told her to try and get a couple more hours of sleep. She replied,

"I woke up a while ago, but I didn't know what time it was.
So I sang Happy Birthday to myself, just in case."
