Take a photo. Record the chorus. Capture the confetti if you must.
Then put the phone down.
You came to see a live performance, not to produce a vertical documentary called My Forearm at the Arena.
The people behind you did not take out a small loan to watch your battery icon turn red. They wanted to see the artist. Not your cracked screen. Not your notifications. Not your thumb trying to find focus while the best song of the night happens behind it.
Your phone has seen enough.
Let your eyes have a turn.
