Here's a light-hearted analogy ... It's a bright, sunny spring day. You're in a great mood. You take a blanket and picnic basket out by the river to enjoy some peace and quiet, and maybe read a good book while enjoying the sound of the water streaming downward toward a small waterfall. Life is good. Then a swarm of flies come by because they smell the food. They invade your picnic basket and start buzzing your head. You try to shoo them away, but they get more persistent. They're right in your ears and in your face .... BZZZZZZZZZZZZZZ!!! Finally, you give up. You close your book, fold up your lawn chair, pick up your picnic basket, and go home. I like picnics, but I don't like flies. ;-)
