On Anxiety Before the Concert

What if I arrive too early?
What if I arrive too late?
What if I can't find parking?
What if I look like a loser?
What if it's too small a venue and I can't blend into the crowd?
What if it's too large a venue and there are too many people?
What if there's a mistake with will call?
What if I can't find will call?
What if I don't know where to go?
What if I am the only one there alone?

Slight anxieties beforehand.
