Faith and Miracles

Do you believe in miracles? I do. I was raised to believe that miracles can and do happen. But is the word, "miracle," used too often to describe non-miraculous things? Is it a "miracle" when your doctor helps you through an ailment, or is it, if you are a religious person, God giving humans the knowledge to cure the problem? Is it a miracle when you get a good parking space, luck of the draw, or just simply a good thing? What do you think and why?
