I’m always disproportionately annoyed when people portray Seattle weather as stormy. I think I saw like 5 lightning bolts in 6 years living there.

I feel like Los Angeles is a place where people expect ICE to happen because the kidnappings have been happening to my home city for decades, so there’s less media attention to it now. and I want folks to see that in LA, Latine students are organizing major protests & the police are attacking them
LAPD Charges at Hundreds of High School Students in Peaceful Walkout Protest at MDC ~ L.A. TACO
LAPD arrested at least two teenagers protesting ICE raids in Los Angeles yesterday. They were also seen corresponding with ICE agents on Alameda Street during the demonstrations.

*gasp* does this mean I’ll actually be able to use the bus between 7:30am and 9am during the school year? No, probably not…

Maybe I’m confused what’s meant here. My dad’s uncle got his US citizenship BECAUSE he was a POW, captured fighting for the Nazis in Africa. He brought his family over (incl my grandpa who was also in the army). Granted, conscripted soldiers are diff from ICE volunteers. Still, this seems inaccurate
This is essentially what governments did in the late 1900s and early 2000s with respect to Nazis. Whether you were a lowly concentration camp guard or in Hitler's inner circle, if there was evidence you were a Nazi, it was straight to jail with your walker.
It worked.
It worked.
Maybe instead of identifying specific ICE agents who do particularly heinous things, we could just penalize everyone who was on payroll at the agency starting by a certain date.

While I completely agree that the gov has mismanaged this (and many many other projects) I’d like to speak a moment about student housing.
We need more of it and it needs to be more affordable.
Part of that solution is to build more. Whether you like it or not, MTU and UCC make Cork a college town

Editorial - there's more at risk for Cork city centre than the Events Centre 🚨
Events Centre to 'Student Accommodation' - will Cork abandon its historic core?
Will it be a 'library and 250 shoe boxes'?

Just a reminder that this doesn’t mean people like O’Leary aren’t also pieces of shit. They are.
Ryanair CEO Michael O'Leary says he is happy for Elon Musk to insult him "all day, every day" as long as it's good for publicity.
He says the airline has seen an uptick in bookings since his spat with the SpaceX and Tesla boss began.

You should study what interests you. Then you’ll actually get an education rather than a laundry list of skills that you hope will be profitable. And you’ll develop intellectual tools to adapt to a changing world and (hopefully) a mindset to improve and create rather than maximize profit. Maybe.
