Why can’t we kiss over the threshold?

Kissing over a threshold is a superstition that dates back to the 16th century. It is believed that the act of kissing over a threshold will bring bad luck to the couple. This superstition is rooted in the belief that the threshold of a door is seen as a barrier between two different worlds, and the act of crossing this barrier can bring bad luck. It is also believed that the threshold is a place of transition, and that by crossing it, the couple may be opening themselves up to bad luck. In some cultures, it is seen as a sign of disrespect to cross a threshold without permission. Additionally, some cultures believe that kissing over a threshold can lead to the couple breaking up.

In conclusion, although there is no scientific evidence to support the superstition that kissing over a threshold can bring bad luck, it is still a widely held belief that should be respected.
