What fun America is right now. We've a bunch of insipid lunatics running around the building knocking down load-bearing walls because it'll "open up the space" and now we're all just sitting here waiting for the fucking building to collapse on us.
BREAKING: Layoffs begin at US health agencies charged with tracking disease, conducting research, regulating food and drugs.

There’s a snack food very popular w children called Pirates’ Booty. My 4 yo was eating some, & it occurred to me that she only knows one definition of the word booty, so I asked her,
“Do you you know what booty means?”
“Yes. It means butt.”
“So what are you eating?”
“(matter-of-fact) Pirate butt.”

Ok I know nobody cares about this but me, but GOD I care:
1. I have just downloaded your app.
2. You want me to make an account. I don’t want to make an account!

Here's my hyperbola mnemonic: you have equations
(1) (x-h)^2/a^2 - (y-k)^2/b^2 = 1
vs.
(2) -(x-h)^2/a^2 + (y-k)^2/b^2 = 1
Notice (2) has a minus sign on the "h" term. "h" stands for hourglass and minus means NOT--so (1) is hourglass type, resembling hourglass silhouette and (2) is NON-hourglass type

one of my iron clad beliefs is that there are very few actual “schemes” in the world. instead, there are just a lot of stupid, venal people and quite a few of them hold positions of real power and authority
"Corporate leadership is as stupid as everyone else and freaked out about viral shoplifting videos" isn't as exciting as "the pharmacies are doing fascist performance art so they can uh murder all poor people" but sometimes things really are just stupid
