Move-In Day
It was move-in day at the dorms during my freshman year at college. Some frat boy knocked on my door and invited my roommate and me to a party, hoping that we would rush. I shooed him off. Five years later, I was moving to New York with my wife.
We were at the airport and struck up a conversation with a couple that went to the same college as we did. As they also happened to live in New York, we developed a friendship and became best friends.
After several months, we found out that we lived in the same dorm our first two years at college, although he was a year ahead of me. It turned out we lived in the same dorm room our respective freshman years, and he was the frat boy on my move-in day! Story credit: Reddit / youngearthevolution
