Is it normal to rub smooth surfaces on upper lip?
Specifically the Philtrum of the upper lip. I've had this weird habit for my whole life, and I have no idea why. I tried to google it, but even google doesn't have an answer for me (a first). The things I mostly rub on my lip are pillow cases and nails, but I do it with almost everything I come in contact with that's not food, lol. I just want to know if this is a normal thing and if anyone else shares this weird habit of mine.
