There was an "influencer" who "went live" after being entombed for three days. But you kids probably haven't heard of him

You have to block them immediately. The full nuclear. They are only here to make folks angry, and that can’t happen if we lock them out.

Since the first lip sync song on this season of Drag Race was called Enough, and the second was Too Much, I’m so excited to see the girls twirl to Too Little Too Late by JoJo tonight

ok stay with me on this one... sometimes you have writer's block because you're not in Text World. you have to read until you're back in Text World. if you don't read, you're writing in the real world. sentences won't feel right or they'll look goofy. not in Text World though

Can we get an opposition party with ideas distinguishable from parody?
I am introducing the Quick Recognition (QR) Act, which requires ICE and CBP officers to wear uniforms featuring QR codes. When scanned, the code would generate a digital ID displaying the officer’s name, badge number, and law enforcement agency.

ICE should be unmasked both physically and digitally.

Love learning about all these new names writers have decided are mine, like when they query me and address me as “Dear Agent” or (this one tickled me) “Dear Potential Agent.” My name is four letters long 😭

Lots of folks in publishing are returning to make the books tomorrow, so just a reminder to treat industry people like people in the New Year.

Everyone is just trying their best. ❤️

I feel like if your pronouns are they/them, A) that’s rad and good for you, and also B) you should say “they/them’s the breaks.” It’d be funny. thx 💕
