Suspicions

I have many suspicions, many things to avoid.
Such as putting umbrellas up indoors.
I have to dodge the cracks on the pavement, to avoid any more bad luck!
I can't walk under ladders, or put shoes on the table.
I have to avoid the number 13 completely. I'm scared to crack a mirror, and I have to pass on chain mail, just in case.
Black cats are an exception, but I can't look at their eyes.
Honestly, I'm terrible, I cannot lie, I always feel uneasy when I do these things, like I'll have bad luck for the rest of my life.
