You and Vinnie attended a birthday party, you are both invited. There are a lot of people in the group, so you stayed close to Vinnie.

Minutes into the party, a red-haired girl walked towards Vinnie and started flirting with him. Vinnie didn't care at all, he continued to ignore her. Vinnie went to his friends and talked to them.

The girl looked at you, your eyes and hers as she walked towards you, judging you from head to toe.

"Ah, so you're his girlfriend?" She smiled, falsely.
