first get you a packpack. Then when you buy them from the store. take them to your car if you drive. Put them in the packback and he will never know what you buy. Then get you own trash can for your room Get the black trash bags and put use diapers in there. As long you dont poop in them there be no smell. When its trash day take the trash out day taken them out that night before or when you get it. Just depends how city sanitary process is. Then you should be ok.
