Miley Cyrus inspires a lot of open letters. Irish artist Sinéad O’Connor wrote not one, not two, but three online missives to the 20-year-old pop star. The theme of those notes ranged from the status of psychiatric care in the modern Western world to whether or not Miley and Sinéad had enough time in their schedules to meet face-to-face (spoiler: They don’t.)

Now Miley’s the muse behind yet another open letter, but this time the focus isn’t on her controversial performances. Instead, Miley’s getting schooled on grammar. Her teacher? Indie rock artist Sufjan Stevens. The 38-year-old is best known for his 2005 album, Illinois; you might recognize the song “Chicago” and its hypnotic “all things go” chorus.

Beside performing catchy folk tunes, Sufjan also appears to have a passion for grammar. In his letter to Miley he corrects an error in her song “#GetItRight.”

“One particular line causes concern,” Sufjan writes, “‘I been laying in this bed all night long.’ Miley, technically speaking, you’ve been LYING, not LAYING, an irregular verb form that should only be used when there’s an object, i.e. ‘I been laying my tired booty on this bed all night long.’”

Don’t sweat the error too much, Sufjan adds. “We all make mistakes, and surely this isn’t your worst misdemeanor,” he writes. Unlike in Sinéad’s heated letters, Sufjan goes out of his way to praise his fellow musician calling her “the hottest cake in the pan” and advising that she never “grow old” and “live brightly before your fire fades into total darkness.”

Also, learn your tenses.
