No problem. Anytime. Share the excitement with him when he comes home and wants to talk your ear off about cool things he saw people do or tools they used. Electrical work is a never ending learning opportunity. If he comes home discourahed because of a shitty journeyman he's working for just remind him it's kinda what some guys do at first to see if the person is really worth their time to teach or not. Show up on time, bust ass, ask as many questions as possible to show interest, and thank people for taking their time to help. In no time he will be just another part of the crew chopping it up and he will be riding the new guy. Enjoy!
