I'll never forget, many years ago my husband at the time had spent the entire day out on a rowboat fishing with his brother. All day, more than 8 hours. These two men rarely spent time together. That evening I asked him how their day was, etc., "What did you guys talk about?". His response was "Nothing". How do you spend all day with your brother and not talk about anything? I remember thinking that if I were out on the lake in a boat with a woman we would know everything there ever was to know about each other by the end of the day.
