My best friend and I will be retiring soon. She wants to start traveling with me as her husband doesn’t like to go anywhere. She smokes. Heavily. I can’t see any nice way to tell her I can’t stand the cigarette smoke. She seems to think if she rolls her window down a few inches, the smoke won’t get to me. Wrong. I want to tell her in a NICE way that this won’t work if she smokes in the car or in hotel rooms. Again, it has to be in a nice way. Please give me your suggestions, or if you have been in this situation, how did you deal with it?
