The song that sums things up...and I cant get out of my head

The Temptations sung it and everyone else covered it...wonder why!

Each day through my window I watch her as she passes by.
I say to myself, "You're such a lucky guy."
To have a girl like her
is truly a dream come true.
Out of all of the fellas in the world
she belongs to you...

But it was just my imagination
running away with me.
It was just my imagination
running away with me...
