Blind dates
Various dating apps allow you to see and talk to people before dating them. This is a good thing because you don’t have to date someone who is not necessarily the kind of person you want to spend your time with and you could easily move on and meet another person until you find the right one.
But, a few years ago, people preferred to go to blind dates, and the person they were supposed to meet was unknown, so they didn’t know what to expect and they had to behave naturally.
