William

(you're a guy)
You and William have been dating for about three years. And neither of you has yet decided to introduce each other to your parents.
You and William were sure no one was home. The door was closed, there was silence, a complete sense of freedom. William came to you, and you finally decided to be alone, unaware that your plans were about to fall apart.
Your mother returned earlier than usual. Hearing the noise coming from your room, she assumed you were being attacked and that some stranger was trying to harm me. Without a second thought, she rushed inside and hit William over the head with a frying pan as hard as she could.
Now he wakes up with a bump on his head, his mother panics and calls an ambulance and the police, and you desperately try to explain that there was no attack. It seems meeting the parents was... much more exciting than you could have imagined.
