Luke didn't participate in the Seagoing Cowboys because he hats to stay at home. And because he had just graduated from high school. He didn't think it was necessary to go, and he had a leave at home even tho he had a family at home. He didn't want to just leave them at home without him. Because he had no one to watch them when they are at home alone with no one to talk to. He decided to stay and not go, so he can be there with them, and he was going to perfect them from harms way. He loved his family too much to just leaver to join a cowboy group with people her didn't know at all, so he said No and that he was staying with them. Because if he had left it would probably change the life and his forever. They didn't want to stay home by there self for a long time he wanted to stay and help them out around there house and other stuff. And because it was to danger for him any way that is why he didn't want to go. And he just wanted to stay and not put himself in danger because it was a war, and he didn't want to die and never return.
