Back when he was a not famous 14-year-old, current ultra famous musician Dave Grohl wrote a fan letter to Ian Mackaye, who was the lead singer of DC hardcore heroes and sXe pioneers Minor Threat. Ian recently found it and sent it back to Dave, who promptly posted it on the Foo Fighters' Twitter.

Oh, internet, how we love you.

Look what my hero Ian Mackaye (Minor Threat/Fugazi) just found: a letter I wrote to him when I was 14! Haha! pic.twitter.com/Ak8gxZz5m6
