It's Good to be Home

"Is it dumb that I thought the bigger the tire, the higher the number should be on the air gauge thing?" I ask the DNB.

"Ehhhh," he responds, in a weak attempt to be political. "It would be if you understood physics."

"I took physics in college and tested out of chemistry," I announce proudly. "Can you describe it as it relates to a shower curtain? That's what really cemented physics concepts for me."

Instead, he goes with a balloon analogy. I see his lips moving, but the words aren't really making sense. Plus we've already done a good bit of work on a bottle of Boone's Farm.

"Oh well, I don't really care," I finally say.

"But baby," he goes on, determined that I will understand the finer points of tire pressure and related theories. "Think of it like this: pounds per square inch. The word 'per' means divided by. So if you have one pound per two square inches, that's one half. Then if you add one, it's two pounds per three square inches."

"Yeah, I'm not with you on that." I mean the latter part, because I do know that 'per' means you divide. Sheesh. "Can't we just leave it that the bigger the tire, the more air you need to fill it?"

"No!" the DNB says emphatically. But he slumps back against the couch all the same.

"I think the moral of this story is that I'm not filling my own tires again?" I ask him.

"Agreed."
