It reminded me so much of emails from bosses in my life: short, blunt (almost rude?), typos galore, weird formatting, bad grammar, “sent from iPhone”, etc. It’s almost as if, once you get to a certain level of power, you no longer need to try. Because the only reason people spend time crafting a well-written email is to look powerful, mature, professional. But if you’re already a powerful professional, I guess technically you don’t need to make an effort. And if there’s no other boss above you, you can do whatever you want.
