After reading John Walsh's post, it made me think of things that my mother used to say, like:
What you do in the dark will come to light!
Everything that is known in not told, and everything that's shiny is not gold!
Don't write a check that your butt can't pay for!
A hard head makes for a soft butt!
If you make your bed, you're going to have to lay in it!
What kind of sayings did your mother tell you?
