world. if we hear a bird singing, we can change that to the passive voice, and observe that bird song is happening. if we see a beautiful cloud, translated it into the passive voice, we observe that clouds are happening. if we are very thirsty and are just ready to down a big glass of water, we can observe that thirst is being satisfied. then when we get pretty good at this, we can start with the negative stuff. anger is happening, sadness is happening, fear is happening, instead of i am angry, i am sad, or i am afraid.
