if u dont let um in n ur apartments rented, cant they get ur landlords permission or something? am not sure what the laws r in the us. best advice i can give is try n stay outta trouble mate lol. n i know its difficult but if u start gettin shit from ur neighbours n police dont start kickin off with em cos it'd make things worse. did ur neighbour ever grass u up for smokin weed before? if not just get stoned n chill gud luck mate
