This has properly irked me for years.

Why do people insist on touching you (often on the arm or, if they are history's greatest monster, your face) to somehow prove that they are cold? Do you think that I'm so banal as to not believe you that you feel cold? Never mind how boring it is to hear 'It's cold' or 'It's a bit chilly today!' repeated ad fucking nauseum, why insist on touching people with your manky, withered, icy appendages?

Exceptions of course to attratives who do this. That is perfectly OK.
