Also, going on your phone disrupts the "flow" or the "way". It's like, trying to pause earth, send a text, and it still pick up right where you left off. You can't do it. And you miss all the experiences that just came and went, including those that could have helped other people. When you finally pickup your head again, you're suddenly on a different wavelength than the rest of the world.
It's also disrespectful looking at your phone in social engagements (I sound like an old person, but I'm not.) Looking at your phones usually means one of two things 1) What's on my phone is more important than talking with you, or 2) I'm bored; you're not entertaining enough. My reply to #2 YOU'RE not entertaining enough. Yet here I am, praying for you while you're on facebook.
