If something feels right, it is right. What makes us truly moral human beings is not how we feel toward one another but how we act. Everyone likes to hug a cute little baby. I am reminded of Rabbi Kushner's story of the couple who asked him to officiate at their marriage. The Rabbi refused to change the words, telling them that yes he understood that many marriages end up in divorce, but there was something more important at stake here than how they might feel about one another in 20 years.
Commitment transcends feelings.
It brings us to a different level. Some call it love. I submit that Michelle loves her Mom very, very much. That is why she is sticking by her through these trying times. If, at times, she feels bored or angry or impatient with her ailing mother, that is part of the human condition.
