It kind of pisses me off to have unused tickets to anything.
It doesn't matter that I got it as a prize and had not intended to go to the event.
I had accepted that I would not likely use the ticket I got that is picture here. The logistics were tricky. I made other plans.
But, when I find out too late that I had friends go and that I could have possibly hitched a ride, that only serves to make it worse.
