You’ll want to appear as if you’re high status and busy as well and take your time in replying to her, too. You don’t want to appear too available as this makes you look needy. You’ve probably done this before already, thinking that if you didn’t reply to her fast enough, she might lose attraction for you or she might be upset with you because you take too long and that might ruin your chances with her. Come on, admit it, you’ve done this before; everyone has. It’s not a rule that should be followed to a tee, but it should be loosely followed, and if done, should put you into an attraction-building position.
I’d look at my message, make sure it had been sent and had actually gone through.
We become obsessed with checking our phones every couple of minutes, and we don’t take control of our lives.
Instead, we let our cell phones control how we live!
At the same time, though, you’re making a bit of a joke about her not being around, so it’s a good way to ask something semi-seriously while at the same time coming across as playful. Using “lol” is a similar thing I like to do and recommend.
It’s basically the same idea as the smiley face and can also be used to lighten the mood.
