Earlyitis syndrome
Earlyitis is when you can't help but show up way too early just because you think you're super cool for it, and you end up looking like a total lunatic.
I showed up at the concert an hour before it even started. I had time to eat, drink, and still had time to feel like I was crazy.
I arrived at the park 30 minutes before the game started. I just stood there looking confused.
I got to the meeting spot 2 hours early and just sat there like I was waiting for something important to happen.
