As a non sufferer of triskaidekaphobia, the number thirteen doesn't bother me at all. I find it rather amusing that people change their house number to 11A or 15A, that some streets skip thirteen as a number altogether or that some buildings are without a thirteenth floor. Though the number four is feared in Chinese culture, people of eccentric persuasion are said to be at 'thirteen o'clock' which is rather fun. The Reception Cell at the former Maitland Jail is numbered thirteen, and I doubt fun was ever an option. 666 seems more apt.
