Charlie Kalson is one of the pre-made townies who resides in Mesa Flats, one of the neighborhoods shipped with The Sims Pet Stories. He can be made playable by befriending and asking him to move in, or by marrying him. As far as personality, Charlie is extremely outgoing. But he is somewhat sloppy, lazy and serious, and quite grouchy.
Charlie's interests, lifetime want, skills, and turn ons/offs are randomized at the start of the game. It is only referenced in the game files that he has no interests, lifetime want, skills, or turn ons/offs. Charlie shares the same last name with Adriana Kalson, a townie also from Mesa Flats. He has the same facial structure as Irfan Zaidi.
