Do Indonesians know the difference between water drainage/a river bank/a sewer and a trash can?

Let me ask you something, have you done any extraordinary changes or contribution to help our country?! I hardly think so. So please if you attempt to undermine our nation I suggest you shut the hell up and leave this section immediately. I never insulted other country's drawback unlike you, so next time don't ever judge our culture from the negative perspective.
