What is an unusual habit you have that you convince yourself is normal but can’t tell anyone about?

An unusual habit that some people might have could be arranging items in a very specific order or pattern, such as organizing books or groceries by color or size. This habit might not seem immediately odd to the individual, who believes it brings them a sense of calm and control. They might hesitate to share this with others for fear of being perceived as obsessive or overly meticulous. Yet, to them, it’s a perfectly rational way to keep their environment harmonious and to manage stress. This routine can become a private ritual that they engage in regularly, reinforcing their sense of normalcy even if they choose not to discuss it with friends or family.
