Unfortunately this is true. But I think people are more in it for the excitement of texting and maybe to meet up. Then when push comes to shove they chicken out. People are good at making plans and promises, just very bad at keeping them. So a mix of cowardice and lack of manners.
Read so many times about people not showing up, even if it's just for a meet and greet. Now if your not friends and see each other regularly, people can just block or ghost you too without any remorse.
Manners and values are dying in this hook up society.
