I had a sobering experience the other day. I got a call on my cell while driving, pulled it out of my pocket and then tried to see who it was on caller ID.
What a dumb ass. Never again. I almost ran a red light and a woman was about to push her bike out and walk across the intersection.
I have vowed to make that my one and only warning. If I answer the phone, I'm going to try to pull over first, and if not possible, NO WAY IN HELL am I going to look at the screen. They can tell me who they are...
