two memorable movies come to mind.
Number one, the sci-fi flick Alien. Because I don't care how miraculous it is to grow a living thing inside of you, it's still a living thing inside of you poking and pushing it's way around so much a woman's belly can resemble a water balloon filled with angry gremlins.
And Ghostbusters, because the rest of her is about as happy and fluffy as the Stay Puft Marshmallow Man waddling heavily through the streets of Chicago, (or is it NY?) happy and jolly on the outside, but ready to stomp on the next person who says how cute she looks.
Trust me, angry gremlins in your tummy and feet as big as Michelin tires do not feel "cute".
But please feel free to tell her how her lovely glow (sweat and acne) really emphasizes her femininity (robust curves). Just make sure you are offering a hot fudge mint chocolate chip cheesecake sundae with a warm chocolate pop tart on top while you say it.
