宮崎ハロー英会話のミニレッスン 2:Superstition

Today is Friday the 13th-Black Friday! It’s a very unlucky day in western countries. There are many superstitions such as it’s bad luck for a black cat to walk in front of you and never walk under a ladder. In Japan, one popular superstition is to never cut your fingernails at night. If you do, you won’t be able to be with your parents when they die. Actually, I don’t understand this superstition…What other Japanese superstitions are there?
