The Limits of Loyalty to Daddy

My son and I are the two holdouts, meaning we the only members of the family who are still so sick that we are either sleeping most of the day or lounging around watching movies. I felt that we had really bonded because we were able to commiserate together throughout the day. We snuggled up on the couch to some movies, and he really seemed to enjoy having Daddy there to suffer through this with him. Then came bed time. Normally my wife and I switch off reading to different kids, and I was my turn to read to my son tonight. But he stopped me and explained that he wanted Mommy to read to him tonight and all nights when he is sick, then we can switch of the nights when he feels well. My first thought was: "Where's the loyalty? Didn't we suffer together?" But I later thought: "Well, I guess if I were in your shoes I'd want Mommy too." It softened the blow a little.
