Why do you have spares?

[Tim Roden]

Tonight was an interesting night. First, as I was running on a floor I have never called on before, I tripped over the bleachers where it juts out so one more row of seating can be pulled out. I tripped and tore up the knees on my paints. Fortunately I had a spare in the locker room and a I changed into them at halftime. Then my partner who has been using the same whistle for 5 years had it break in his mouth. He had to go for his spare whistle. Why bring extra stuff? You don't know what can go wrong on any given night.
