2 years back I was scheduled for a game at a school I'd never been to. My partner that night was someone I had never worked with, but I knew that he was hearing impaired. I left early to be sure we had time to do a good pre-game so that I'd know what to expect.
Naturally I got lost and got to the site with about 6 minutes on the pre-game clock. Ran in and got changed. Made it to the floor with 3 minutes on the pre-game clock. My partner had captains and coaches ready for our pre-game meeting (he couldn't run it as he is hard to understand in a noisy gym). Ran the meeting, had a brief chat with the partner during player introductions and away we go.
Despite the rushed circumstances, it was one of the best games I worked all year. Partner was in position and managed to communicate well. All my worries were unjustified. It went so well I considered being late to all my games.
