Two weeks later, his friend called, stuck on a banking site. Leo didn't even hesitate.
Pop!
"Safari menu," he said. "Settings. Go to Websites. Click Pop-up Windows. Change the dropdown to 'Allow.' Then close the window. You're in."
Leo was a writer, which meant he lived in two places: his cluttered apartment and the even more cluttered landscape of the internet. But today, he wasn’t researching obscure 19th-century poets. Today, he was trying to buy a last-minute train ticket to see his grandmother.
He found the perfect fare on a budget rail site. He clicked "Confirm Booking." Nothing happened.
And somewhere deep in the code of the internet, a tiny, blocked pop-up was finally set free.
Leo clicked on the desktop to make sure Safari was the active app. He looked up at the top-left corner of his screen, past the colorful traffic light buttons, and clicked in the menu bar.
