Does anyone else hate it when people don't reply to messages?

Want to start by saying I'm not calling anyone out on here, just venting about other crap. It's like, it's not "socially acceptable" to text directly after sending a message. Or even any time afterward, because all it does is give the impression that you're needy or that you don't have a life/even that you're a little creepy. But those things aren't always true, at all. Actually, if you're really interested in a conversation you're having with someone and they suddenly stop replying for days whilst still post on social media/you hear from friends that they've been speaking with them you're kind of left wondering if you've said something wrong/ you've upset them. i don't get it. leads me to believe I'm the weird one. every. single. time. Is it wrong to enjoy talking to someone/be disappointed when they don't respond?
