RE: Looking for advice
Good question, it's either in you or it's not. I don't understand some of my friends who don't go when they can go or are wishy washy about going. Me, it's in me, part of who I am and I'd addicted.
Perhaps bring some footage home with you from a sit? I don't know, when telling of your sits, get real excited, real emotional (if it's in you) and maybe it'll affect him more. That's a tough call and I wish you the best.
