I saw Zuckerberg sitting alone on a picnic blanket and joined him. I had meetings later in the day, and happened to be wearing a suit (most people in Silicon Valley wear jeans and T-shirts). Zuckerberg told me to be careful not to get grass stains on my trousers and made some more room on the blanket for me. Then, without prompting, he said: “At least in the movie they got that part right. The first time I met venture capitalists, I really was wearing pyjamas.”

Great story. And the Brits spell pajamas weird.
