So I think of myself as a very good driver. I am always careful & pay close attention to everything going on around me. Well on Monday I did the most boneheaded thing I've ever done behind the wheel of a car. I rearended a guy at a stop sign. I was not on the phone or doing anything other than driving. We were at the end of an off ramp. I was sure he had already pulled away from the stop sign, so I was watching for my opening to merge onto the road. I saw my spot, excellerated & BAM right into his bumper. Now I'm not sure how or why I thought he had already gone. I always sit & watch for the car infront of me to go, pull up to the stop sign & then look. I don't know if he started to go & then stopped or what happened. He was OK about it. I appologized instantly cause I knew I was totally in the wrong. He was quiet for a while, and said it's fine, but you need to watch the car infront of you not just the one's comming at you. I was not about to argue because his car actually had a mark in the bumper, my car has no damage, and I could have gotten a ticket. I felt stupid & horrible. I still can't believe I did that, I'm always careful. I have had a lot on my mind lately & I guess I just wasn't paying attention. I hope I'm not the only one who has ever done something so stupid.
