Oops I Stayed

Oops, I stayed.
Oops, I stayed.
I came for one drink.
That's what I said.
I'd leave before midnight
And go straight to bed.
Then you walked in and smiled my way.
I checked the time, too late.
One drink turned into eight.
One kiss made me forget the time.
I said I'd leave at midnight.
Oops, I stayed.
