Denise...don't discount your effort. Perhaps it didn't make a difference that day, but people can take a long time to digest concepts that initially don't agree with them. Maybe you did make a point. Don't give up trying (though I truly doubt you would).thinking that maybe that would make an impression on the child. Nope. Unfortunately our conversation did nothing to change the child's behavior.
This thread has been really interesting in a scary sort of "wake up" mode. I've always been a helmet believer and shudder when I see helmetless heads--particularly on kids riding on the wrong side of the street <grrr />. I did crash while wearing my helmet. I got knocked out and was only coherent after arriving in the ER. I have no recollection of the ambulance ride although I was told I rode in one. The helmet kept my injury to a small concussion.
When I read the postings here, I realize that in comparison my injury was minor. Still, without that helmet it wouldn't have been.
