When was the last time you shot yourself in the foot, figuratively?

I once was driving with my husband on a saturday morning when we drove past a woman and a man who were in the process of getting their car towed because it broke down. You could totally tell she was humiliated. He spouse was dressed and it look like she was maybe on her way to drop him off to work when the car broke down.
Anyhow, I could see her trying to cover her chest by crossing her arms and her hand over the side of her face.
He hair was uncombed, and she had on high water sweat pants with holes in it. On top of that she had on a guys tee shirt and you can tell she had no bra on and was wearing thin flip flops on a hot tar road. She looked like she just got up and figured she could drop him off at work and return home before anyone could get a good look at her.
I remember pointing her out to my husband and explaining to him that is why I refuse not to groom myself before just dropping him off somewhere. You never know when you may be forced out in public because your car broke down.
So when was the last time you learned that being hasty can turn around and bite you in the rear?
