We Are The Physics all my friends are jpegs

I'm now in the background of more photos than I'm in actual photos of myself
Tagged, tagged and assorted, a peripheral face
Everyone's a camera, must deliver visual evidence
A good time was clearly had by all
Incidentally, you're accidentally missing an event trying to capture a static version of it
You don't like me much, so let's keep in touch
I don't like you much, so we'll keep in touch
So there it is, flung up on the internet
Nobody's even bothered to rotate it
Who are half these people?
And now we're friends, yeah, we're friends
Without the inconvenience of ever having to be in your company
In fact, I see nobody
You're just a list of names as dead pixels
You don't like me much, so let's keep in touch
I don't like you much, so we'll keep in touch
I cut off the headroom, I crop out the legs
I tag you, I tag me, all my friends are JPEGs
