#5 Never Respond to Text Messages
Even more annoying than the guy who responds with “K” is the guy who never responds at all. It takes all of five seconds to respond to a text and, if you have enough time to read it, you have enough time to answer it. If it’s something that is going to require an actual conversation or you are actually busy, then state that up front. It’s not necessary to respond to every single message ever but she’s bound to get irritated if you rarely or never respond and will begin to assume the worst.
