Sis tells me both Mom and Dad had come upstairs when she went to bed. They never do that. She me if I was faking being asleep? I say no. It had been a...very hard day and falling asleep was easy. Me being fast asleep was comforting to parents. Sis is in a good mood. . Sis says " I cannot believe Dad allowed you to sleep up here. I tell her "I was blown away!" She has a surprise to show me.
