ok a few months ago my father-in-law moves in with us after the death of his wife,he is legally blind,so really has no choice.I have 4 children and my husband and I smoke but not in the house,after he moved in he asked me if he could smoke in his room with the window up,I of course say yes(he did just lose everything)but now everytime he opens that door or sometimes just walking bye you smell nothing but smoke,its aweful and nasty.How can I not hurt his feeling or make him uncomfortable because he does pay 400.00 a month to us.help me please
