Sometime send a dozen roses, and have a card with it read look in your purse and place jewelry in her purse. I did it one year, and it still is talked about. What is sad is that that sort of action should not stand out so much from the norm that a few years later it is still talked about in this way. Don't ever mention weight. If you do, well, we will see you on the other side.
Weight is touchy for women, more so than men.
That's mainly because they are competing for our attention with other women. Women are more open and honest with each other. We men do not get up in a group to go to the bathroom. If we asked another guy to go to the bathroom he might think we were off a little or even gay. But women, they like to go and may not even need to use the bathroom.
