There are two guys who come into my library that look like Santa. I wish that I could figure out a good way to sneak a picture of them so you could see, but you'll just have to imagine.
Good Santa has a fluffy white beard and likes to wear red and green. He works as a professional santa, so near Christmas, his beard gets even fluffy, but he wears it all year round. He smiles and is very friendly. When kids come up to him, he is very friendly and gives them a little card that says "I talked with Santa" that has his picture on it. It doesn't have any of his business details, so it's not even like he's just trying to make money out of it. His wife says that his address is on the back, but it's just white... snow... the north pole. He is always Santa-ish.
Bad Santa has a gray beard and his hair is greasy. He comes in in a dirty t-shirt that barely covers his belly. He does not smile or look friendly. He sits in a chair with one leg up in a way that makes me think he's airing out his balls. I do not like bad Santa. I wish he would stay away.
