Phew! That was a close one!

Driving in to work today, I suddenly noticed that the cars ahead of me went from speed limit to crawling about 50 yards ahead. So, naturally, I put my brakes on. Not too hard. My purse did not go flying or anything, but I had a serious reduction in speed. Automatic reflex when I brake suddenly is to check my rearview mirror. My heart jumped and my stomach flipped when I saw a big old truck speeding toward me! I was simultaneously aware of 2 cars in the right hand lane, one just a car length back and one barely a car length ahead. No way was this truck gonna fit in that space! Instinctively, as I checked my rearview mirror, I lifted my foot off the brake to get ready for another quick tap. At the last millisecond, the truck swerved into the right hand lane and whipped around me. I still don't know how he missed me and the two cars in the right lane, but I couldn't breathe for like a minute. Thank you, God, for your grace!
