I've spent a few hours yesterday at a cheerleading competition where Elder Spawn is competing with her high school JV squad.
It is truly astounding how many people are walking around, face buried in their phines, no f--king CLUE who is around them, what's going on, where they are, etc.
Overheard one cheer mom suddenly explain "Wait, where are we and how did we get here? Isn't the exit back there? I'm lost..."
Pro Tip: Eyes open, look up. You don't always need to have your head in a swivel, but it'd be a decent idea to be in the world around you, and handle your Twitter updates later.
