I'm going to hide a spider in my boyfriend's room as light hearted revenge for him being messy
What kind of revenge are you seeking?
I'm just seeking some sweet revenge. I knows he hates spiders.
Taking revenge on your bf by hiding a spider in his messy room just to get back at him is not okay. Confront him about his messiness if it bothers you so much.
Nah, it's light hearted and I'll put it somewhere that it can't escape.
If you care about your boyfriend you would not do something that would scare him. If his messiness is bothersome to you, either communicate that or stop going to his house.
