My girlfriend has a new yoga instructor names Mark. He is such good shape, I feel a bit weird about her going to his classes.
Don't worry bout that.  She has to have some sort of fantasy in her life.  Don't you have any ever?
Well yes, my instructor Marissa is so dreamy. But still... I see the way she looks at Mark.
Well know that it isn't any different from you checking out other girls too.
