My sister is very strange. After good night, my sister's personality, hairstyle, height, face, age... All the places I can see will change. I can't remember when it started. I noticed that my sister is very strange. But maybe I might not have remembered the strangeness before I remembered it. At that time, I probably hadn't noticed my sister's strangeness after growing up a little, and I realized that my sister was really strange enough.
