I never do because I can't! As soon as somebody points a camera at me my face gets tense and I just go blank :blank.
My cheeks do that too! They poof up like hamster cheeks, my smiles truly horrific. Nowadays though I don't mind so much. Yeah the photo might be horrendous but it will still remind me of a fun day out.No, I never show my teeth when I get photographed. For one thing, I don't like my teeth....they're straight and everything, but I still don't like them. And my cheeks look like a chipmunk's when I really smile O.O. I try to avoid cameras when I can, anyway.
