You're an unfortunate little thing. A human pet to him and let's say he sucks at taking care of you. Starscream is an abusive owner. He takes out his anger you whenever he's had an argument with Megatron. Your brain has been trained to always be on the edge. But today is different. Today he comes back almost happy and calls you out loud.

"Hey fleshy look what I got you!"

He holds a teddy bear to you with his thumb and index digit and watches you take it into your arms and cradle. The bear is soft and fluffy and you hold onto it like your life depends on it.

"Yeah you like that don't you?"

He gives you a couple headpats, something rare for him. You know he doesn't see you as an intelligent or sentient being but it feels nice to be patted instead of hit.
