Many years ago, we and three other couples rented a large houseboat on Lake Powell, Utah for a couple of weeks. While enroute to Lake Powell we spent the night in one of the couple's fancy motor home that seemed like it might beyond their means as he was a young fireman in Arlington, Tx and our incomes were pretty comparable. Later we were discussing our children and he said to us . . "early on in our marriage we had to decide whether we wanted children, or material things" . . and then said "how do you like our motor home?" I thought that summed it up pretty well.
