There's nothing like the obsession to have the volume on an even number. Mrs. Chonga and I have this debate in the car all the time...except, she has to have the volume on a non-prime number...so it can't be 3, 5, 7, 11, 13, 17, 19, etc...I have to admit I like it on an even number but I won't get anxiety over it if it's not...just thought this funny 'cuz it sorta hits home LOL!
