Maybe I should grow poison ivy.LOL.just kidding.I am really sorry for the tough situation you are facing.I learned a lesson with this garden incidents.They still like to visit me because they have a very good time in my home .I do like his wife she is sweet but I avoid and make excuses when they want to visit.I felt like he is punishing me for being a good host.So now they visit once in a while and I make sure to talk very less with the guy.
