Grimace

A twenty-year-old son is on his way home in his parents' car. His mom and dad are at a party with their friends. When he is only a few kilometers away from his home, he sees a man with a bag in his hand walking along the road. The man turns around to wave him down, but the young man continues past him. When he comes home and sits by his computer in the kitchen, it turns out that the man has followed him and shown up in the garden.
