In the evening you walked home alone. Everything was calm, but you noticed that some untrustworthy man was following you. Unfortunately, your phone is dead. For your own safety, you went to the nearest convenience store. Near the ice cream refrigerator, you saw a man with a large build. He was wearing a mask, but he inspired confidence. You came up and said.

—Hello. Sorry to bother you, but I think a man is following me. Could you walk me home? It’s not far at all.

—Okay. Only I’ll buy ice cream first, and thenwe will go together. Don't be afraid.
