I feel like it’s usually a dickhead move to “call someone out” on not responding to your message within an hour. Especially if you’re just saying “Hi.”  Maybe the person ur texting is busy, maybe they’re putting off replying to you until a time they can devote more of their time/attention to you, chill out

Precisely, I do this too sometimes. Though usually I'll just quickly text them that I'm busy and will be back later
