Like I have to sing along whenever Rod Stewart's "Maggie May" comes on. Even if I'm in a dressing room or the market, if it comes on, I sing to it. I don't even think about it.
I consider railroad trestles to be lucky things and I make wishes when I pass one. I also take pictures of them.
When I see a dead animal on the roadside, I touch my forehead and ask for blessings for it on its behalf. That it didn't suffer and that it's soul doesn't remember the pain and fear it felt when it was hit.
I wish on fountains and throw in coins.
In a restaurant I have to fold my straw paper into a tiny square then stretch it back out. I do this until the thing falls apart or my food arrives, whichever is first.
I'll be back if I think of more. And that's the thing, quirks you have may be so normal to you that you have to think of what yours may be.
So what are yours...?
