Sometimes you have a business lunch and you know that everything you say is golden, that you're hitting every line out of the park and your sparkling personality is winning friends and influencing people. You'll smile and laugh, twinkling like a leetle starrr. You'll flash your best big grin like that cheeseball guy in Die Hard. The folks around the table will smile and nod, laughing with you and not at you. Everything's coming up roses and such.
Sometimes, you've just got a big hunk of chipotle on your tooth.
