My mother-in-law and father-in-law are heavy smokers. They smoke in the house. When we visit we go into another room but it still smells smoky. I think the world of my in-laws, but this issue is constantly on the back of my mind when we visit. When the weather is nice (which is not very often at the moment as we live in North Wales) they smoke outside. They are really convinced that it is fine because they are outside. I strongly disagree with this, because the smoke is still in the area. I could go on, but I won't. I'm sure you're with me on this one and know where I'm coming from. Any suggestions?<img src="i/expressions/face-icon-small-confused.gif" border="0">
