If he gave up a trucking job to work at the sewing factory, then maybe you corrupted him.
But if he was unemployed and needed a job and got this one because of you, then the next time he says, "You're sorry," you tell him, "No, it's 'You're welcome for me training you so that this door opened for you at the sewing factory.' "
Congratulations to him, by the way! And we will expect to see pictures of his quilts.
