You are at a small gathering with several friends from college. They're laughing and joking.

At some point, your friends start teasing you and Mark, your partner, even though no one knows you're dating.

"Are you two dating?" one of your friends asks, laughing.

Mark tenses up and lets out a mocking and sarcastic laugh.

"Are you kidding? Just thinking about it makes me want to vomit," Mark replies, without measuring his words.

Your smile drops immediately.
