Weak (A Cappella)

I don't know what it is
That you've done to me
But it's caught me to act
In such a crazy way
Whatever it is that you do
When you do
What you do with
It's a feeling
That I don't understand
'Cause my hearts starts beating
Triple time
With thoughts of loving you
On my mind
On my mind
I can't figure out just what to do
When the coming cure is you
I get so weak in the knees
I can hardly speak
I lose all control
And something takes hold of me
In a daze you look so amazing
It's not a phase
I need you to stay with me
By my side I swallow my pride
Your love is so sweet
It knocks me right off of my feet
Can't explain
Why your loving makes me weak
