Sittin' & Thinkin' lyrics

I got loaded last night on a bottle of gin
And I had a fight with my best girlfriend
When Im drinkin I am nobodys friend
So please baby wait for me until they let me out again

I know the same thing has happened before
And each time it happens, I hate it more & more
When Im drinkin I am nobodys friend
So please baby wait for me until they let me out again

I spent a whole lotta time sittin & thinkin
Sittin & just thinkin bout you
If I didnt spend so much time sittin & drinkin
Wed still have the love I thought we knew

I wont promise the same thing wont happen again
But I can promise, itll be a long, long time till then
cause when Im drinkin I am nobodys friend
So please baby wait for me until they let me out again
