the Damn Garage Door

My condo is above the garage door and when it opens and closes, there is this low hum that can be heard in my condo. Today, I was out all day shopping and hanging out with J and when I got home, the garage door was going up and down. This in and of itself is not that crazy but I got home 2 hours ago and it has been going up and down continually since I got here!

I think I am going insane. This hum is all I can hear.... oh, let it go away, away, away!
