There is a difference between online dating and real dating. Most people on the internet can't see people's expressions, and they can't even tell men from women (except videos). There are many virtual things, and communication is polite, smooth and happy. However, friends in reality know each other. They know each other. For various reasons, they are cautious in what they say and do, which makes them feel very troublesome and tired. Therefore, they will feel uncomfortable for a while and think they are making friends.
