Her son died 11 years ago.
I’m sorry for her loss, but her request is stupid. The lake did not kill her son; an accident did. Accidents happen everyday. If she actually cared about doing something productive, do PSAs on social media about public safety.
My cousin died in 1978 from a skateboarding accident. Did our family scream to have them banned? Of course not.
It’s no more stupid than trying to ban guns because some people are killed by them.
