Uhm, this is surprising. You know your friend, and you know he is usually a nice guy. But you are NOT READY to flirt! You haven't even your first night in yuor new body and now he wants to talk on such an emotional level? YOU barely know your own emotions in your new form. "Thanks, you look pretty cool too", you respond, while shyly moving your hand through your hair. Hopefully he doesn't think this means you are into him, you just needed something to touch to keep focus. This is just too weird. "If you wish, we could play a round too. I just lost against your brother, maybe I can defeat his sister?" Uhh, video games are just such a turn off. You are quite sorry for him, because you "know" they are cool, but whenever you hear "video games" you are just tired and bored instantly. "Nah, I am not into that stuff sorry" "No worries, there are plenty other thigns we could do. If you wish, I am going to make some food, you can try it"
Your sister, in your former body grins at you, exciting about that is going on between you two.
