My grandmother "You can get used to anything except a tack in your shoe".
My aunt "If you can't be a help, at least don't be a hindrance." I have to add that before she started suffering from chronic depression she was so funny. One time Taco Bell barely put any chicken in her enchilada and she disgustedly said "Well, I can see where the chicken ran thru it."
A former boyfriend "You just never know about people". He had some bad relationship experiences like a lot of us and got drafted and served combat in Vietnam. He is one of the smartest people I know.
I hope this was food for thought or entertaining.
