If I get up to go to the bathroom in the middle of the night and Deborah has already gotten up to go, I need to make sure I don't scare her by wondering around the dark house. I could just stay in bed until she gets back, but sometimes I feeling like getting out of bed.
I'll start singing little songs so she hears me before she sees my silhouette. Once she acknowledges me I say, long lines at the bakery. And soon we are both back asleep.
