Knock, knock, knock, oh
Knock, knock, knock, oh
Knock, knock, knock, oh
Knock, knock, knock
Oh, been trying to let it go
Trying to keep my eyes closed
Trying to keep it just like before
The times we never even thought to speak
Don't wanna tell you what it is
Oh wee it felt so serious
Got me thinking just too much
I wanna set it off, but

It's this 1 thing that's got me trippin
It's this 1 thing that's got me trippin (you did)
This 1 thing my soul may be feeling
It's this 1 thing you did oh oh
It's this 1 thing that caught me slippin
It's this 1 thing I want to admit it
This 1 thing and I was so with it
It's this 1 thing you did oh oh

Hey, we don't know each other well
So what I keep thinking to myself
Memories just keep ringing bells
Oh oh, Oh oh, Oh
Hear voices I don't wan to understand
My car keys are jingling in my hand
My heart feels a clicking towards your door
Oh oh, Oh oh, Oh

It's this 1 thing that's got me trippin
It's this 1 thing that's got me trippin (you did)
This 1 thing my soul may be feeling
It's this 1 thing you did oh oh
It's this 1 thing that's caught me slippin
It's this 1 thing I want to admit it
This 1 thing and I was so with it
It's this 1 thing you did oh oh

Maybe I just can't believe it
It's this one thing you did oh oh
I can't deny, tired of trying
nothing left to do but keep on seeing you
I'm hoping you can keep a secret
For me, for me, for me
But what you did, yeah

It's this 1 thing that's got me trippin
It's this 1 thing that's got me trippin (you did)
This 1 thing my soul may be feeling
It's this 1 thing you did oh oh
It's this 1 thing that's caught me slippin
It's this 1 thing I want to admit it
This 1 thing and I was so with it
It's this 1 thing you did oh oh
Oh oh oh Oh oh oh
Oh oh oh Oh oh oh

Knock, knock, knock, oh
Oh
Knock, knock, knock, oh
Knock, knock, knock, oh
Knock, knock, knock, oh
Knock, knock, knock

It's this 1 thing that's got me trippin
It's this 1 thing that's got me trippin (you did)
This 1 thing my soul may be feeling
It's this 1 thing you did oh oh
It's this 1 thing that's caught me slippin
It's this 1 thing I want to admit it
This 1 thing and I was so with it
It's this 1 thing you did oh oh 

It's this 1 thing that's got me trippin
It's this 1 thing that's got me trippin (you did)
This 1 thing my soul may be feeling
It's this 1 thing you did oh oh
It's this 1 thing that's caught me slippin
It's this 1 thing I want to admit it
This 1 thing and I was so with it
It's this 1 thing you did oh oh
Oh oh, Oh oh
Oh oh oh Oh oh oh
Oh oh oh Oh oh oh
