My sister sends a text, telling me she is making lasagna, and asks if I will bring a cake. “Sounds great!” I readily agree. “When?” There is no response. I know we are celebrating my mother’s birthday early, but I have no idea when, so I don’t know when this cake will be needed. I could call my sister, but that sounds difficult. Will she be busy? She is a teacher, and she is busy a lot. She gets up early and seems to be in constant motion from the time she gets off work until she goes to bed.
