I still have visions of the young girl who unexpectedly turned her bicycle in front of my vehicle over 25 years ago. By some miracle the girl only received minor injuries despite my vehicle striking the back of her bike and tossing her into the ditch. I also was driving under the speed limit on a county road and the evasive action I took ended up taking me into the ditch and hitting head on into a concrete culvert. To this day I am super sensitive when children are present and happen to be walking or playing on a sidewalk or the side of the road. I instinctively assume a defensive driving posture anytime I see children. You never know what may happen. LE, it doesn't sound like you did anything wrong. Best thing for you to do is move on and remember the importance of driving safely and defensively.
