It was a crisp January evening in 2015, and Alex had just finished getting ready for what promised to be an exciting night. He was heading out to meet Emily, who was not only his girlfriend for tonight but also someone he had met through a mutual friend. The concept of "tonight's girlfriend" was a bit unconventional; they had agreed that they would meet, have a great time, and part ways without any strings attached. It was all about enjoying each other's company without the pressure of a long-term relationship.
