Hot ear

So, I have a question.  It is about ears.
I can now tell the emotional state of my sons based on the colour of their ears.  And I have even found myself giving other people the inside scoop on ear reading.  This feels very strange.
First of all, Ben and Davis feel the heat of summer most acutely in the, mostly upper, cartilage of their ears.  This is excruciatingly annoying and intolerable to them.  Hot ear is bad.
Secondly, when they are anxious or massively bored, their ears get hot.  Hot ear is bad.  Hot ear dilemma  trumps all others, and the original stress trigger trades place with this hot ear stressor.  Hot ear = red ear.
Therefore, slightly pink ear is low agitation; deeper the shade of red, the more intense the feelings of frustration and anxiety.  Or, just plain hell hot weather; we live in Vancouver, but their ears say we live in the deserts of Australia.
Tonight Davis and I were at a class, one that, I grant, can be boring and thank goodness is almost done.  He'd had a long day at school and while most Tuesdays he can tolerate the additional school-like environment, tonight was too much.  It was also warm today, and he is always warm, even on cool days. He's the little furnace that warms my hands before bed with his hands.  So does Ben.  And my hands cool theirs - mutually agreeable arrangement.  I like holding their hands because Moms just like that, temperature unrelated.
So, Davis scooted around on his chair with wheels (either a really smart or really dumb chair to give a kid, I don't know) and tried to cool himself down by licking the back of his hand and rubbing the spit on his bright red burning hot ears.  Priority one now became finding an ear cooling strategy.  Part way into the class his ears were so hot that an increase of spit wasn't working one bit.  I suggested we go to the washroom and cool those ears.  No, he was sure it was too far and the effort would only make him hotter.  Finally, after a discussion of how spit is body temperature and therefore would be unlikely to effectively cool an ear in a non-air circulating room; even if his chair has wheels, the highest velocity he could achieve safely would not suffice in counter balancing the intensity of ear on fire.  And it's gross.  That part he didn't either get or care about, but he agreed that the puddle of spit in the palm of his hand wasn't working.  Everyone around us was pretending they were so interested in the topic of healthy snacks they didn't even notice. On the way down the hall we found a water cooler with super cold water.  In the washroom he cooled his ears and feet and hands and face. He calmed.  We returned, with a cup of cold water as back up.  Later he apologized to the teacher for breaking his pencil and trying to flee on a wheely chair in hot ear frustration.  She smiled.
This all consuming hot ear problem sure does effect behaviour as I have seen on many warm days leading to sleepless nights, or stressful situations that hit the hot ear switch.  So, a cold pack under a pillow slip is a life saver, and guess what Davis' favourite Christmas present was - an awesome purple hand-held fan from ToysRus that sprays cool mist from the little ice cube tray in the base.  Oh, the joy.
