“It‘s a curious fact, because Friday is a day of work and Sunday is a day for pleasure, so you would expect people to enjoy Sunday more, right? But we don’t. It’s not because we really like being in the office and can’t stand strolling in the park and having a lazy brunch. We prefer Friday to Sunday because Friday brings with it the thrill of anticipating the weekend ahead. In contrast, on Sunday the only thing to look forward to is work on Monday.”
