I'm planning to run from house to house and ring their doorbells before dawn.
Why are you going to disturb people by ringing their doorbell?
It's just a prank, bro. That's the best time to wake them in their house.
This is just not a nice thing to do. Despite knowing when they are home to annoy, you are doing something rude showing up at such hours.
Nah, I can't wait to be thrilled by the fear of their reaction.
I doubt they will be afraid, more likely annoyed. Some houses have cameras now so if you plan on pulling a prank like that, expect to be recorded and caught.
