Dear Skinny Girl:

Do not look into my shopping basket with that expression. I really don't need you thinking you can judge my groceries just because you refuse to eat. I don't understand why you're browsing in the food aisles anyway, when we both know that the only thing you're going to buy a pack of sugarfree gum (mmm, filling). You stick to your world and I'll stick to mine.
Later gator,
H.
