Itchy ears are a sign that someone is talking about the person. Whether or not someone is being polite depends on whether their left or right ear itches.
Right ear itching is a sign that someone is being cruel to the individual who has the itchy ear. When someone is being kind to someone who has an itchy ear, the left ear will itch.
There are many different superstitions around certain body areas that itch. If the right hand’s palm itches, money will be received; if the left hand’s palm itches, money will be disbursed.
