Mimi wanted to stop laughing but she couldn't, not when the reason for laughing was funny as hell. She was dating Victor? What kind of bullshit conclusion was that?
Victor was a pompous asshole, a man she would never date even if an apocalypse hits earth and the male population comes to an end, all except him. She would rather die than repopulate the earth with him. A man that cannot acknowledge his mistake was not worth her attention!
"Alright, that's enough!" Her laughter was not funny to Draco anymore because it was beginning to feel insultive - she was unintentionally hinting he was stupid for making the wrong judgment and he was a man of pride.
Mimi shut her mouth with immediate effect. She understood that just because this particular breed of gangsters was being cordial to her doesn't mean they weren't capable of harming her. She didn't want to get hurt.
