No, I do not want to share a dessert

bebe Me loves some dessert. I know, it's an accepted practice (especially among women) to be out with someone and suggest sharing a dessert from the menu. I've spent my life trying to figure out a delicate way to say, "hell, no!" and how to determine how well I have to know someone to say it. Even if I've just barely met you, you can share my entree, my salad, my appetizer and please share my drink, but leave this girl's dessert alone. I mean, you really don't want to mess with anything that makes a girl's eyes roll back and makes her say, oooooh... do you?
