Once at a hill station, on the lawn of a big hotel, three elderly women were playing cards. A fourth approached and she asked if she could join them. They said,"Of course, you are welcome, but there are a few rules." And they handed her a printed card, with four rules on it 1 - Never talk abot mink coats, because we all have them. 2 - Never talk about your grandchildren, because we all are grandmothers. 3 - Never talk about jewelry because we all have precious jewelry. And 4 - Never talk about sex - what was, was!
