Cover art for At Home lyrics by Crystal Fighters

I think that this song is more about seeing friends or loved ones while they are away from home, and you had always said you were going to see them but had never had the time or money to do so. The "No No No…. Yeah yeah yeah" is showing the disbelief that the person has actually turned up at their doorstep. The I left alone, i left the world i was running. is to display that the pressure of their life had gotten to much and they decided to pack it in at short notice and abandon their old life and travel with their friend. The leaves falling et their feet shows that they can now see things around them as the beauty they are and when they were home it was just a thing that happened and was ignored but being in a new environment makes everything interesting again. there is a lot more here but I don't have the time to go into more!

I love this song and really like your interpretation. Hah it's changed how I feel when I listen to it.
