If I wasn't so tired, I could probably see it as a solution to the long standing physics problem. The irresistible force of Three Seat Bob is slowly but surely demonstrating what happens: The immovable object eventually bends outward from the waist up, half way into the aisle, where the cart can smash its entire arm instead of just the elbow. The second time someone brushes their bum past my face on the way to the toilet, I resist back, hard. The message slowly passes through the layers of fat and 10 minutes later Three Seat Bob notices, "Sorry man, this is all the room I have", he says.
It's been a long day, I'm grumpy, I want to get home and my usual good humor deserts me. I'd been doing okay up to now. I never said a word when he stated that "he'd warned them not to put him in a middle seat" like it's the airlines fault he doesn't fit. I ignored his complaint about how "the seats get smaller every year", because not so long ago I used to tell myself the same lie to excuse my own expanding waistline, but this is too much.
"No", I reply, "It's all the room you have, plus half the room I have".
Bob goes quiet for a second, I think he expected a sympathetic response, an ally in his war against the injustice of a $150 seat that doesn't comfortably fit his 300 pound frame, but if I was the wrong guy on the wrong day before I sat down, the smell of his armpit soaking into my shirt is not making me any happier.
"At least you have the aisle", he says, as if this is the logical conclusion to his need to take up half my seat. I laugh. Not a happy chuckle, more a wry snort, but a laugh all the same. He doesn't like that much either.
"I guess I'm not all that sorry then", he says.
"I guess you're not", I reply, redoubling my immovableness.
