Can I report my neighbors to the front office?
Why are you going to report your neighbors?
They are disturbing the peace of our dormitory.
Neighbors should be respectful to each other. They should not be disturbing the peace for others. Reporting them is the right thing to do.
I plan to complain. They are being too loud and sometimes they smoke marijuana.
I think you are doing the right thing. You need to say something before it gets even worse.
