Mona Lisa Myth

Ignoramus in art, you'll say of me. I've tried real hard, but now I still can't see that Mona Lisa's mythic, mystic smile, known to bewitch folks even from a mile! Seems to me she parts her lips daintily to let out a half hiccup gracefully or a vulgar burp, hyperacidity, or hide nicotinic teeth artfully! Nothing there in her mouth's coy symmetry remotely resembles a mystery. Maybe she's got dental deformity. Y'see, I took up ortho-dentistry !
