I get that people match for validation, and then don't carry on a conversation. But initiating a conversation, then not replying is just fucking weird. Are these people just mental cases?
This has only happened twice so far, but both times they sent a message late in the evening, and I replied the next day. Maybe they were just bored that evening, nothing to watch on Netflix?
It made me think though, it's probably a good idea to generally wait a day before replying to weed them out effciently without wasting too much time.
