I lived in a house My height on the walls Right next to my sister's Who lived down the hall At night we would knock On the wall that we shared Sleep head to head I miss being there Oh, o oh Oh, o oh This is what I used to know Oh, o oh Oh, o oh This is what I used to know My piano teacher She lived next door We tried and failed to make her fudge when she got sick I quit taking lessons cause I got bored I used to like her son, but he turned out to be a dick.. Oh, o oh Oh, o oh This is what I used to know Oh, o oh Oh, o oh This is what I used to know Oh o oh oh oh oh oh I snuck out once But it wasn't worth the worry I went down the street To meet a boy who wasn't Good enough for me My dad had a moustache That he let me shave He thought he could help, but He just wanted to save us From each other 'cause We had gone mad Forgotten the good things Forgot what we had Oh, o oh Oh, o oh This is what I used to know Oh, o oh Oh, o oh This is what I used to knoooooow This is what I used to know
