An old boss of mine would find people who left their computer logged in and would send an email to the department from it saying “I love you all so much!”
I worked in a different office and didn’t realize that’s what was happening. I just thought the Russian guy was happy to be in America.
One day when I was visiting home office I ran into him in the elevator. My lead introduced me to him. I blurted out, “Oh the guy who sends the I love everyone!” emails.
He promptly started swearing and cursing our manager and saying what things he would do to him if he caught him in a dark alley and ranted for the duration of the elevator ride. Then shook my hand and said “Nice to meet you!” and went on with his day.
