you make short statements like this but never expound apon what you say? If you are adept at electrical work and can make money from that then that's great but why mystify electricity?
If he knew something about electricity he would be a professor,doctor or something else at the university, people like this just talk shit and are sick! Unfortunately end up in garbage, cant controll their brain. Lost mind and end up like a sicko! Just ignore them! The only reason people listen to them is the curiosity, WHAT IF he know something we don't...that's it!
I have been there myself, and have seen this behaviour before...have friends like this to! The thing is people like this cant have any friends, they end up alone, sick...!
5 years from now, he is of the market, cant have a normal conversation with him...
