I'm going to play a revenge prank on my brother and his girlfriend on valentines day
Why do you want to prank your brother and his girlfriend?
I just want to be an asshole to them because I feel like it!
You shouldn't play a prank like that on a special day like Valentine's Day. You should be respectful of your brother and his partner.
I don't think they will notice, also I just want to be a dick towards them because I can.
It's wrong to be mean for the sake of being mean. You should just let them enjoy their Valentine's day together.
