Tom` Diner

I am sitting in the morning At the diner on the corner I am waiting at the counter For the man to pour the coffee And he fills it only halfway And before I even argue He is looking out the window At somebody coming in It is always nice to see you Says the man behind the counter To the woman who has come in She is shaking her umbrella And I look the other way As they are kissing their hellos I'm pretending not to see them Instead I pour the milk I open up the paper There's a story of an actor Who had died while he was drinking It was no one I had heard of And I'm turning to the horoscope And looking for the funnies When I'm feeling someone watching me And so raise my head There's a woman on the outside Looking inside does she see me? No she does not really see me Cause she sees her own reflection And I'm trying not to notice That she's hitching up her skirt And while she's straightening her stockings Her hair is getting wet Oh, this rain it will continue Through the morning as I'm listening To the bells of the cathedral I am thinking of your voice... P.S. And of the midnight picnic Once upon a time Before the rain began... I finish up my coffee It's time to catch the train
