When was the last time you got to tell someone ?I told you so.?

When was the last time you got to tell someone ?I told you so.?

I'm a lifeguard at a government pool facility. Everyone thinks they don't have to listen to me, but I have rules to enforce. If anyone runs, I yell walk. People like to run, I yell walk and watch them fall. Every single time "I told you so"

When I told my best friend her (now ex) boyfriend was a toxic man and he was probably cheating on her and it was true.
