Hello from the griddle

So, here I am - on the griddle. The always ebullient Bojack said last class he was going to go to someone else. Called the guy by name, and told him he was up for this class, and here he's called on me. He skipped me two classes ago, and now here I am. So, it's a little disconcerting, so I'm commenting on the feeling as I'm in the middle of it.
My chest is a little tight, and I'm remarkably aware of the restricted airflow through my sinuses, and a sort of tightness across the front of my nose.
Bojack is actually quite merciful. Tension in my shoulders as I'm leaning forward. First part of the problem is done, and here we go on to second part - getting harder. Some relief - looks like he's not asking any more questions on this section. My tension is easing a little more. Tightness has moved from the front of my nose to my head... and now it's back on the front of my nose. Still breathing. My knees are a little sore - I stretch my legs out in front of me. It's roomy.
Poor A and B are getting screwed on this deal. Poor partners stuck in a guaranteed payment situation with a capital improvement. Poor, poor partners.
Last part of the problem now... but from where I'm sitting, it doesn't look like it's functionally any different than the first part. I've said it's the revenue ruling idea. But I can't really clearly explain the revenue ruling. Working while he explains...
And I figured it out just before he explained it. There is a functional difference, based on how much we're paying to make up the difference on the fixed amount, but at least he explained it for me. Phew! Time for a quick sip of water.
Well, now the adrenaline high is gone, and I'm tired.
Okay, and that's when he comes back to me - so I'm back on the griddle. It's not a sale. It's an exchange. More relaxed now. I'm a talking head. But I drank too much water, and I'm starting to feel a different type of pressure. Ah, what I wouldn't do for a hot tub right now! ;-) As much as this stuff confuses me, I'm really enjoying this class.
