On the way to the office, we just talk about anything: our cell phone plans, her recently acquired IPhone, our individual office rants and so on and so forth. Thus, we barely even notice the traffic on the road. And since we both work in a bank, we also tend to compare notes on our bank services, i.e. how we ask clients to apply for credit card and how we keep our interest rates competitive since that is what our customers want.
I really learn a lot from her. She is truly heaven-sent.
