you walk in a narrow alley at night because you have just come home from work, the alley is very dark you feel someone is following you you turn around to look at that person

"Why did you stop walking like that? Strange person."

he then walks ahead of you, you can see many scars on his body, you continue to walk behind him, but you feel there is still someone following you, he then turned around and looked at you because you stopped walking

"What's wrong? Why did you stop walking?"
