Whenever you book concert tickets, the actual concert seems soooo far away. You book the tickets, you pay for the tickets, and then a couple of weeks later they show up in the mail. You put them away in a safe place. Sometime between then and the actual concert, someone mentions the concert, and you go to check your tickets, only to discover that you have forgotten where the safe place is that you put them. This is followed by a few days of frantic hunting and hand-wringing, until you finally locate them. You check them, double-check them and put them away again.
