Haha...I'm glad someone brought this up... I would say D because that's a cleanliness issue. If you have allowed yourself to walk around all day with crusty eyes, (assuming this event is at night) then that's just WRONG. If I had to choose the "best" option, I'd say A, cuz it's understandable to have food in your teeth, that's not "unsanitary" but boogies, crust, and ashy lips (again...if you don't kno that u look like Tyrone Biggums there is a real problem) are just gross!
