Today on my drive into work, I was thinking about why I buy The Woman My Father is Married To a Mother's Day card. Everyone seemed to be wondering about it yesterday. If I don't like her, why do I bother getting her a card? The answer is that I do it to score points for my team. Families are competitive by nature. Sibling rivalry does not end with childhood. Even as an adult you don't want your siblings to do too much better than you do and make you look bad. When the people you are competing against are step siblings, this rivalry is multiplied 100 fold.
