The Secret of the Red Ear

I don't know what it is....genetics I suppose. The Red Ear Syndrome...it's like a blinking beacon telling all those around oneself that I AM TIRED!!! My dad has it, I have it and now Marshall has it as well. The funny thing is, it's only one ear....one ear turns bright red and is burning hot...but only when we get REALLY tired. There was never any tricking my parents about my need to go to bed, nor will Marsh ever have that capability. ;-)
