The fraternity of Tailors & Seamstresses in the world are bound by a secret code. Each one is taught to recite special magical words particularly whilst stitching the front pockets of your shirts & skirts. Myth has it that the prayers they so recite has magical powers to protect their customers by blocking others from gossiping and talking against their customers particularly when these front pockets become visible to them. But the magic effectively works, unfortunately, only on the front side.
Abracadabra. Suddenly this explains...experience it yourself. The moment your back turns...gossip begins. Moment your front pockets become visible, there is silence.
