no, the thirteenth has always been good to me.
i usually experience a pleasant surprise of some sort: a good buy, a dinner out or some such thing or maybe i just notice it because it's the thirteenth.
i don't think of myself as being superstitious...i'm not afraid to walk under ladders, to open umbrellas indoors, to cross the path of a black cat, or count cracks in the sidewalk and worry about breaking mum's back if i step on one.
on the other hand, my brunies have abandoned every last task around the house these days. maybe i'm in for trouble ahead.
