Here's mine:
I've had several flirtations with U2 at various points in my life, liking several of their songs and having stints where I'll listen to one of their albums. I even wrote a very positive review for "How to Dismantle an Atomic Bomb" three years before. So that's how I felt about them until November 2006, when I was emotionally spurred. I had seen my brother magnificently perform as George Gibbs in the brilliant play Our Town by Thornton Wilder. If you know the play, it makes you do a bit of soul searching. In that time, I thought about how U2 has that sort of vibe. The eternal questioning. So I starting picking up where I left off and began listening to them again. My obsession grew deeper the more I listened and thought about the music. Frequently, it couples with my already passionate love for the show Avatar: The Last Airbender. I was in pretty deep, but that's only part one.
In late December of that same year, my grandma's health was deteriorating. We had to do an emergency drive to see her and the rest of our family. I had a great discussion with her about the things that tie you to the world like fear, guilt, shame, grief, lies, illusion & earthly attachment, inspired by Avatar: The Last Airbender. She was truly prepared to leave the world, and she even gave her deep thanks to me for the time I spent with her. Throughout that time I was listening to Rattle and Hum & songs like "Stay," "Please," "Lemon," "Kite," "Gone" and "Stuck in a Moment You Can't Get Out Of" heavily. We went home after a while, but on late New Year's Eve 2006, my grandma passed away. Inspired by the song "Kite," I wrote a speech, which I presented at her two funerals in the days afterwards.
U2 became the musical guidance in me through a difficult time in my family and I became the pillar of strength with my guidance for which I given immense praise and gratitude by my family and relatives.
It was then I knew that U2 became a true part of my being and I'll never let that go.
