People have absolutely no fucking couth anymore.
I attended a math club meeting (shut the hell up!) a few weeks ago. As per usual, it was pretty much over my head, but I stuffed my face full of pizza and tried to keep up the best I could. I even managed to say something relevant at one point.
Then some guy arrives. The professor is explaining the problem we were just going over to another newcomer, when guy's phone rings. He quietly answers it, listens for a second, and mumbles "Pegasus Room" - apparently one of his buddies is late, and he's giving him directions. Apparently his buddy is also deaf, because guy has to repeat "Pegasus Room" a few more times, louder every time... while the professor is still talking.
I know. It's just a math club meeting. It's pretty casual - I've got pizza from gums to molars, and it's not like we're in class - but goddamn. The prof shot him a few looks, but guy just kept grazing on his pizza and mumbling into his phone.
In hindsight, I wish I'd slapped the phone out of his hand.
Seriously. It's not a hard concept.
Unrelated image - a building in Dallas. Took this picture on my way back from helping my buddy Chris after a fucking Okie caused something like a 10-car accident and then sped away.
