Apologize, but still try to influence her

You went up to the door of the bathroom. "Hey, Jennifer? I'm sorry. Please forgive me."

She looked at you like she wanted to spit fire at you, but then she seemed to struggle for a moment. "Why should I forgive you for that gross comment?"

"I was just joking," you said. "We both know you'd never actually take your shirt off around me, right?"

She looked like she wanted to object, but then relaxed a bit. What you'd said was true, but you were also phrasing these things as statements, which might have been making the app push her a bit. She bit her lip and said, "Well, yeah, I can see it was a joke, but it's still pretty gross, even as a joke."

"I just want to be a nice guy," you lied. "I'm trying to make friends by joking around. Marcus really wants us to be friends. You want us to be friends, right?"

Jennifer thought about it for a second, then pocketed her cell phone. "Yeah, okay. I'll let it go this time. Just remember that I don't like those kinds of jokes, okay?"

You agreed and went back to the living room, relieved. You'd bought yourself some time, and she did seem to forgive you a lot easier than when you'd messed up in the past. Maybe you could figure out a way to make the app work, after all.
