My mom gives out great advice. This phrase is one that I heard many many times growing up.
"When in doubt, don't."
This phrase has served me well all my life. I use it a lot when I am shopping... that shirt just doesn't seem as cute when you apply it.
Anyway. My mom said it to someone and it was a great way to keep her from being to impulsive. Like marriage impulsive. It really wasn't meant to be.
