hmm FIL smokes. But always goes out the front & sits down on the box thingy that is near the road. I have never thought of telling him he can not smoke when visiting my home, inside or out. He would just go further down the road if I did though. But I hate that he then comes in with the stink on him. I complained once & he replied with a smart comment about me being his mother.. I replied (bluntly) that No I was not, but you are in my home stinking up my furniture when you sit!
