Ah, but you never know where that tract or magazine may resurface after the original person throws it into the trash! I remember a true story about a bum walking along the railroad tracks, down and out, when there, there on the ground was a Watchtower with the feature article entitled "Is God Dead?" Why, that was exactly what he had been wondering that very moment! He sat down and read the whole magazine cover to cover and when he looked up, there were people getting out of their cars and going into a building. Clean people, happy people. He walked over there and was warmly invited to come into the Kingdom Hall and listen to the public talk. No collection would be passed. The title of the talk was "Is your life really worth living?"
That man is an elder and a pioneer today

so, you see, you can just throw your magazines in the trash. The angels will know what to do from there.
