John Mayer was one of Mac Miller's music industry buddies.
But the guitar king decided he had to turn down the chance to memorialize his friend in an end-of-the-year wrap up for a magazine because he realized he didn't know enough about Mac -- and that made him sad.
"Several weeks ago, I was sent an email asking if I wanted to take part in a Mac Miller tribute for a magazine as part of an end-of-year recap. I passed on it, not because I didn’t want to talk more about him, but because I couldn’t; I had shared all the memories I had of him in the brief time of our getting to know one another. I replied to the email and sat in silence for a few minutes. That day, I discovered a new dimension to the sadness of his passing - I wasn’t upset because I knew him well. I was upset because I didn’t. I wish I had more to tell you about Mac Miller. What I do have to remember him by are a couple of beautiful mental photographs that I’ll keep with me the rest of my life," Mayer typed.
