For as long as I can remember, I have had a phobia/superstition about the number 13. I think it went back to the childhood silliness of "step on a crack and break your mother's back, don't walk under a ladder, watch out if you break a mirror, don't open an umbrella indoors. These sound pretty lame. I got over them a long time ago, but for some reason the "13" thing stuck in my mind. If I counted how many sweaters I had to be sure I was covered for the winter, or how many slacks/jeans, if I got to 13, I had to add one or discount one for some reason. Friday the 13th didn't bother me too much, because the number 13 was sort of a personal thing. I just avoided it if I could.
Another illogical superstition (I think I created this one because of my dislike of snow) was snowflake phobia. I have a pair of snowflake earrings and I would never wear them until after the first snow, just because. I also have a plain black long sleeve T-shirt with a single large snowflake on the front. This too, I wouldn't wear until after a snowfall.
One day I read or heard that superstitions showed that I wasn't trusting God as much as I should. I was really trusting in some things man had made up instead of Him.
After this, I learned that the number 13 has several good things going for it. It's a baker's dozen, an extra, something unexpected.
As for the snowflake thing, I can now wear my earrings and black T anytime I want. If you think I'm foolish for doing these things, at least I had the desire to change. Now that's freedom.
