Both of the Baxter Boys are good honest lads, who have fallen on bad times and each has their own interests and talents. Charlie takes pride in what he does and that showed through in his interview earning respect from his future employer. From your comments, he has also earned your respect which makes me happy.
You are right, Stacy knows nothing about car mechanics but his brother, Charlie's future employer, does. Stacy considers himself to be a good judge of character and recognises that in the Baxter Boys, could there be more to it.
I like your comment about higher powers being at work here. We often hear about fate, karma and God working in mysterious ways, I don't know what truth there is in higher powers being at work, but I do know that things happen that we cannot explain, is this one of them? I'll let you readers decide.
Thank you for your thoughtful comments, I enjoy reading them.
