I tend to sail through Friday the 13th with no more than average bad luck, which sometimes makes people look at me sideways. Family lore has it that this is because I was born 13 days after Friday the 13th, so am somewhat immunized. Karma (or Murphy) apparently will have its due, however, because my birthdays are generally pure hell.
(Seriously, I avoid going places on that day. Ever. Because – well, the tamest thing that’s ever happened is chickenpox. Once it was enough snow to build a snow fort, when everyone swore that should be impossible, and as for some of the other things that’ve happened….
Well. “The building was on fire, and it was not my fault“, isn’t just a Dresden quote.)
I suspect everyone in the world has a date like that. Or a combination of date, time, place that makes them say, “Oh, hell no. Not doing it. Nope.”
So characters ought to, as well. Think about it. If they had anything approaching a normal life, they must have had their share of bad luck, too. Which implies there are certain situations which are seen as Out To Get Me. Not for any specific reason. Just because.
So… what would your character detour down three separate intersections to avoid, Just In Case?
