The only time you should message or text “Hey” is someone that you know. Even then, it’s a face palm. When did messages or texts become so impersonal? It’s “Hey” then a dick pic. That makes it personal, right?!
With online dating, a simple “Hey” is an immediate turn off for me. It shows you have little interest in me as a person. Sharing interests is the best way of opening a conversation.
“Hey, I’m Marge! You seem like a pretty cool person. And your interest in knitting is something I’m into. What’s your favorite yarn?”
“Your taste in music is fantastic! Have you seen any of your favorites in concert? I’m George, btw!”
