Impossible

I've got a habits I know 
Of picking on your faults 
It fakes a lot to make you mad 
But if I tried I'm sure I would 
And if my Sunday gets too dull 
Would you allow me to be 
Awful, I mean miserable, impossible ? 
That's what friends are for 
I've noticed just by watching other people 
While they're talking to each other 
Since this party started 
I've been feeling pretty shaky 
Like a fish out of cold water 
In a glass of coca cola
