I love a person who replies right away. It means they actually want to talk to you. Don’t keep me waiting. I don’t want to waste my time on someone who doesn’t want to talk to me. If you don’t want to talk, just say so. I’ll understand. It’s better than to keep me waiting like an idiot for your reply. If you’re busy, tell me so I don’t bother you. I don’t want to come off as annoying.
