I'll give you one but first I MUST give one on my sister-in-law and then one on my wife.
Sister-in-law, in here early twenties was pregnant for the first time. She had so much trouble with morning sickness that she couldn't even keep down the anti-nausea pills so the doctor gave her some anti-nausea suppositories. She had to call her mother to find out what to do with them. (
Oh how I wish she had called me!)
Wife, some years ago when we first had two cars, my wife had a Malibu and she didn't work. As most of you know, Chevrolet used two different keys, one for the door and one for the ignition. After she locked herself out of her car the second time with the keys in the ignition, I had a second door key made for her to carry in her purse. I knew that women instinctively always grab their purse even if the keys are still in the ignition. Sure enough, a few weeks later, she called me at work to say she had locked herself out of her car again. I asked if she had her purse. She said, "Yes." I said, "So." She said, "So what." I said, "So don't you have the spare key in your purse?" She said, "Oh, bye."
Now me, It happened when I was just 11 years old. I had just read "Huck Finn" where he signed his name in blood. That seemed sooo cool & I wanted to do it. I made great preparations, got a safety pin for the puncture, some string to force the blood to the end of my finger, went outside and found a good seat on a stump in the front yard. I carefully wrapped the string arounf my left index finger, starting at the base. I opened the safety pin, sat on the stump, placed my left hand on my left thigh, pulled back and jabbed. However at the last minute I chickened out and jerked my finger out of the way, thus jabbing the pin deeply into my thigh.

Now I try (very hard) to think ahead to determine all consequences.
