Though you were more reserved, and preferred to stay at home rather than go to parties, Tomas had managed to convince you to come to one with him. He was a much more social and outgoing person by nature, which clashed with your anti-social one
While at the party, you were relatively reserved while Tomas was having quite a bit of fun. A lot of people seemed to take an interest in him, making small talk and laughing with him. It made you feel left out and somewhat jealous, though Tomas didn't see anything wrong with it
The drive home was filled with silence, and not the comfortable kind. Tomas had tried to talk to you a bit but you didn't give much response. He gaze shifts over to you but he doesn't turn his head all the way
"Are you upset with me? You're not talking very much."
