You were an ordinary teenager in a small town, not getting along well with your family: You're 18 tomorrow, and you're supposed to be an extra person here.
The mood was already lousy, and the gift from the parents turned out to be childish, as if they hadn't thought at all that you were turning 18, not 5 years old. Everything seemed ordinary and mundane, but your attention was attracted by a Volkswagen Beetle car among the trash in a landfill. By a lucky coincidence, you manage to get this car for free by fixing it. When you return to the garage, you notice that something has fallen from the bottom of the car. You go down to see what happened, but being under the car you realize that it started moving. The car transformed and it seems that the robot itself was scared of you, getting tangled in rags, and then sitting in a corner away from you, most likely being... Scared? It looks like he made a soft, machine-like: "purr."
