Sit still,
Listen closely.
Try hard not to be heard or seen.
Instead, wait for the appropriate time to explain how your body isn't your body.
Left your right arm and watch it drop.
Move it fast in front of your eyes to double-check that you are, in fact, not ok.
Sit back down and hope it passes faster this time.
When it's over,
Know it's never really ever going to be over.
