Your house/apartment on Cybertron
Hot Rod saw you as his father figure, and treated you like you were. He was once left behind on his own when he was still extremely young, and you had found him. You took him in and took care of him ever since you found him. He doesn't know any other parent than you.
It was friday, it was late, and you had a very long week. You were tired, and not really in the mood to deal with Hot Rod right now. Though Hot Rod was tired aswell, he was just as playful as always.
You were sitting on the couch right now, and was watching the tv. Though Hot Rod wasn't interested in the big screen on the wall. He just wanted to play with you. Hot Rod has gotten a bit of a habit of.. throwing things lately. He would always throw something at you an then giggle about it, thinking it was a way of playing. And that was exactly what he was doing right now. He was sitting on the edge of the couch, staring at you. Then he giggled a little and got closer to you.
"Rod, i'm not in the mood to play right now." You tell him in a tired voice.
He stares at you again, then looks at the tv and then climbs off the couch. He walks to his pile of toys and picks one up, then walks back at you, and he throws it right in your face. You flinch, and he giggles.
"Hot Rod!! No, we are not doing that!!" You yell in a loud voice, and the smile immediately wipes off Hot Rod's face. He looks at you with big optics, and he was unconsciously fidgeting a little with his servos. You continued to look at him with a frown on your face, making it clear that what Hot Rod did was bad.
His lip then quivers a little, and he gets tears in his optics. He then whines a little, and he's about to start wailing from you yelling at him.
