We all know people with smiles that can light up your heart. Erstwhile normal looking people with smiles that make them look beautiful. But what happens when it's the other way round.
There's nothing as shocking and instinctively yet momentarily repulsive as noticing an ugly smile. I knew a man famed for his good looks, admired by hundreds of women, yet his smile was horrible, it was a total shock when I came across it first. It totally took away all his beauty. It's hard to focus on an ugly smile but it's rude to look away when someone is smiling. There's no easy answer. Then there's the girl in work with the laugh that sounds like she's choking her last breath in space, but that's another story.
