“My mom moved around a lot as a child due to the nature of her dad’s job, so she met a lot of kids over the years, but never really had long-term friends. In second grade she met a little girl and they just clicked, becoming really close in the time she lived in that town. Eventually, they moved again, and when she was in fifth grade, the class project was to get a randomly assigned pen pal and write to them. The girl assigned to her was her friend from second grade. They lost touch again when they both moved.”

“When my mom went to college, it was in a town near where her family was living at the time. By this point, they had moved about six or seven times all over the United States. As part of the college requirements for freshman, she lived on campus with a randomly assigned roommate. When she walked in to meet them, it was her best friend from years before! They’ve now been best friends for most of their lives, and still get together for a weekly coffee and chat.”
