After my boyfriend of six years was killed in a car accident a few months before graduating from our university, I went to the store to pick up something before I left for the airport to go back to our hometown for the funeral and other stuff. A man literally laughed at me as I passed him and said “Smile! It can’t be that bad!”
The audacity still kind of floors me to this day. I learned from that incident to never assume you know what is going on with another person.
