My friend said, 'I finally learned to say no.' I said, 'That's great! What was the last thing you said no to?' He said, 'A coworker asking me to cover their shift.' I said, 'And?' He said, 'I said no. And then I said yes. And then I said I'd think about it. And then I said yes again. But the first no was real. I felt it. It was beautiful.'
