le we were at the beach one day, we met a group of people and spent several hours hanging out with them. We never exchanged phone numbers or email addresses, we didn't share much information about ourselves other than our names and where we lived, and we didn't connect on social media. I didn't even have my phone on me at the time. However, when I got back to New York and checked Facebook, I saw that two of the people we met popped up in my "People You May Know" recommendations.
