8 months ago when H was drawing a smilie on our bathroom mirror about every 4 days or so, I didn't say a word. If I got mad at him during the time it was there, I'd erase it. (yes I was this juvenile) lol
Yesterday when he did it, I walked up behind him, hugged him, kissed the back of his neck & thanked him for being so thoughtful.
Keep trying.
