Through this column, I’ve been fortunate enough to teach my faithful readers some life lessons. A few weeks ago, I went straight to my social psychology textbook and discussed the power of the situation. Last week, I gave my East Coast audience an introduction to California culture — and probably shocked any investment banker readers by proposing the notion of going to work in khaki shorts and polo shirts. I don’t need to check the records to know that my dad rocked such a combination Monday morning. Or he might have hit the gym in the morning to blow off steam and then gone straight to the office in workout clothes. Those are the only two possibilities.
