Have you ever had to call 911?

Not for me thank God, but all the time at work. I have a half sister (same dad) who was a 911 dispatcher we weren't close growing up but i spent a few summers at her house and we look like twins. She died at the height of Covid. I was at work one day and had to call 911 because a guy in camouflage was walking around pointing a rifle at people. She picked up and i knew her voice i just kept it professional and just said thanks big sis right before we were about to hang up. And i bet she was like what the hell lol
