I will never forget when my grandmother was washing some of my clothes and things as a teen-ager and she was really thorough when she did it. She saw some grass stains on my pants and I promised her that I got them playing sports, but somehow just did not believe me. And kept mumbling...."I don't what what kind of young lady gets grass stains on the knee of her pants". :-)

I laugh now, but at the time, I was made she didn't believe me.
