And one of my brothers didn't marry until he was 34. He and his wife moved to California for a job and had two children. They were the only couple in their subdivision with children under 10! Everyone else had dogs. I was visiting them a couple of years ago. We went to pick him up from work, and his then three year old ran towards him with his arms outstretched crying "Daddy, Daddy!" My brother picked him and gave him a big hug, and then said to me "Dogs don't do this." He absolutely loves being a father.
Bull-$hit!! I know dang well that I couldn't handle it mentally or physically. And I work in our family business throwing 50 and 100 lb. bags around all day.
