I want to scare a girl
Do you like this girl?
I do, but I just want to give her a good scare.
Scaring someone can really be a lot of fun. Don't be too intense or you might put her off.
I don't care. I think she needs to be scared of me.
I think if you like her, that is the wrong attitude to have. Scaring her in a fun way shows you like to have fun and are funny.
