Superstitions and believes are sometimes very powerful. Most of them do no real harm, but it must have been horrible if you actually belief in superstition in the former times . One of the the most weird naivities I know was maybe the burning of the witches or the selling of indulgences by the catholic church. We are so blessed that science enlightened us in all that years 😊 .. Most of us 😉 .. So I assume you believe in the 13 to be a lucky number 🍀 .. Ohh while I see this leave here, in Ireland it is a sign of luck, but in Asia the number 4 is a unlucky one 🤞.. Weird and funny world indeed
