Throwing stones is great but you must find them from a reliable source. Coming in and shouting "There's not enough stones being thrown here!" doesn't make everyone start throwing stones at anyone but you. If you cannot come in and say, "I have a really good stone here! It's not mine but I found it in a really good place! Is it okay if I throw it around a bit?" then your stone probably isn't a very good stone. You probably picked it out of your own garden or the garden of that house down the street which you are always looking at. Stones in that garden are often made of old bits of slate and that travels fast but it breaks up too easily. To find a suitable stone, first try a rock quarry and try to pick up the most really massive stone you can see. Quarry stones can be thrown around as much as we please but don't throw too many slate stones in a room where people usually throw quarry stones. Someone might flatten you and then we wouldn't be pleased. If you think that being flattened might find you some special atention, go ahead but just take note of the stains on the floor and don't say that nobody warned you.
