My favourite superstition from our family is : If you walk under a ladder you'll hve bad luck all day long.

This one is pretty basic and simple, but it's true. Had a situation on a christmas eve when the ladder was standing right by the tree and i walked under. That day i ripped my favourite dress and broke my phone. Bad Luck. Since the i belive in this superstition.
