Parents don't understand kids and kids don't understand parents. My parents were divorced when I was really young and I went to live with my dad.
Mark Hoppus'Built This Pool' was an idea that I had for a song starting several years ago, and as we were in between takes of recording something, I was actually holding a guitar at the time, and I played this silly thing, and sang the lyrics to 'Built This Pool' kinda in the background.
