Of course the type of person to ride a scooter on the sidewalk and hit someone will spin it as a lesson to others. It’s too bad you weren’t sued so you could learn to accept so e responsibility.
Maybe. But even so, I do think the comment might cause some readers to behave more safely. Someone saying "I did this thing and it had a bad outcome, don't be like me" has more impact that someone saying "Don't do this thing."
What's the point of anon334455 commenting except to warn others to be careful?
