I'm a grouser, as are many of my friends. I'm willing to admit that I'm not perfect, and my wife has put up with me for nearly 30 years, an admirable feat on her part.
At the same time, I've earned my right to grouse. The drama that comes from her side of the family, with her six sisters, is extensive. They can make a mountain out of a molehill in nothing flat.
Everybody grouses from time to time even women. :-)
