The other night I accidently cut my finger working in the garden. After the bleeding stopped, the doorbell rang. Some neighbor kids were walking dog's to raise $ for Animal Friends. Our Dog is going blind in one eye, and basically hates everyone in the world besides us. I did not feel comfortable sending him out with them alone, so I walked with them.
Anyway, while we were walking, in the dark, I didn't realize that my finger had started to bleed again, and I wound up getting blood all over my FAVORITE shirt.

I called my sister and asked her if there was any hope of salvaging a light colored, cotton shirt with several bloodstains. She gave me what sounded like very strange advice - but it actually worked!
She told me to spit on the bloodstains and rub them out with a paper towel. She said since it was my blood, that my spit would remove the stains. I totally thought she was kidding me!
I was totally shocked when it actually worked!
