first of all donot use a grinder the kid who told u that is dumb as shit it will pull straight through. second if u take the dime in ur hand u will relize it is enough for mayb (big mayb) 2 bowls. now break off the desired amount for one bowl ( by one bowl i mean enough to fill the bowl 3/4 to all the way up). put the rest back in your bag. now pinch a piece of the small nug u are holding and pull. the amount u have pulled off is about as small as it should be broken up (any smaller and u will suck it through the hole that is y u dont use a grinder when breaking up bowls). now repeat that process and there u go. then there is a method i like to call re-greening the bowl. to do this u take a tooth pick or a very small tool such as a toothpick and flip the weed in the bowl this will allow u to light the weed that has not been burned yet giving u a clean hit just like the first two. i suggest u do this once the top on the bowl has a little gray in it. Now about smoking in your house. bathroom is only good if it has a window. outside very good idea. or window in room with door closed. now a good tool so that u dont get the room u smoke in to smell like smoke is by makeing the insturment i will now describe. take a papertowel roll and stuff 5-6 dryer sheets in it. then take one and rubberband it around the end. now when u need to exhale u breath into that and it will make the air passing through it smell good thus not smelling like weed.
