Now we all know second hand smoke is awful but I have a dilemma in that I have plans with a friend who's a heavy smoker this weekend and I'm 8 weeks pregnant. I haven't told her so I can't exactly ask her not to smoke. I'll probably just have to cancel but I'd feel rubbish as I haven't seen her in months! I know she'd understand when she eventually finds out but just wondered if anyone had tried excuses to ask friends to stop smoking without giving the game away?
