Thanks everyone for your advise.
Mike you are absolutly correct, honesty is the best policy. I should give my DW credit that she was correct in telling me to chalk the shower. Just like when she asks me if this new outfit makes her look fat. Honesty, I think NOT.
Kathy, you are also corect also that DW will know she was right when I do chalk the shower no matter what I say. The problem is that I have to say something that will let her think she was right with out giving her the licence to remind me of it everytime the subject of camping comes up. I can see it now, "Hey honey, lets go camping this weekend. I want to use the shower that you finally chalked after I told you to do over a year ago."
You see my problem.
Any other suggestions? What other Mars and Venus issues has anyone experienced camping?
Help,
MM
