Were you paying attention to the road when this happened?
No, I was a bit distracted.
Not paying attention while driving can be dangerous for the other drivers on the road if you are not careful. Always keep your eyes on the road when you are driving.
I can't believe you're blaming me for this.
No one is blaming you over this incident, only reminding you of the dangers to other drivers when one does not pay enough attention. Distracted driving causes many accidents every year, so please try to keep distractions to a minimum.
