I was in a park and a lady loudly called out "Anyone who wants an ice cream come over here". I headed over with several others. She handed out ices to them all then asked me "Who are you?". I realised the rest were all her family. 30 years later I still cringe.
I once taught an 8 am college class. So many grandparents died that semester. I then moved my class to 3 pm. No more deaths. And that, my friends, is how I save lives.
