Oliver crawled quickly to his parents and gave them both a big hug. His mother's hairy breasts felt strange to nuzzle against, but somehow comforting. He released the hug and stood there admiring them both. "You both looks so beautiful! I guess we can all embrace being apes for good. How you feel?" In response, Janet gave her son a satisfied grunt. Then another. She hooted like an animal and pounded her chest. Oliver then turned to his father, expecting a more clear response... and he screeched happily, followed by hugging Oliver tight and lifting him off the ground. The realization kicked in: his parents could no longer comprehend language like a human. And what's more, it would soon happen to him!
Oliver's friends caught up with him at that point. Samson asked, "What do we have here?"
"My parents lost their speech! They're on their way to becoming full apes."
"It will happen to all of us", added Tim.
"Are you sure you won't miss it?"
Jim thought for a moment. "It no bad. Monkey n-- oops-- I mean real monkeys in the jungle have a different way of communicating."
Marcus noted the slipup. "Don't fret about it. We're all going through a rocky t-- tr-- change right now."
"I just hope it happens at the same time", concluded Oliver. "Monkey don't wanna go too far behind."
Outside the hospital parking lot, many of the half-transformed patients were crowding the streets, celebrating their new, unbelievable freedom. Not only from the usual jobs and responsibilities, but also from intelligence itself! As the subjects change, they slowly lose their comprehension of human concepts bit by bit, consciously feeling it happen to them in real time. The mind was always the first thing to be affected by this treatment, as evidenced by the children eating bugs and digging around in the dirt at the beginning of the school year, and the adults acting feral and devoid of shame as soon as they step out of the hospital, before the animal features begin to appear. Now the whole town was about to give up its humanity. As soon as a batch of subjects left the hospital, more volunteers were walking over each other to get the treatment.
Oliver had a feeling things would get too chaotic for comfort very soon. He called to his friends, "Let's spend the day at the park! This will get out of control before you know it." Margus and the others gave their agreements. Oliver patted his mom and dad on the butts, urging them to go with, and they seemed to understand. Daniel and Janet leaped onto the hoods of cars and climbed over the short fence, followed closely by the younger ones. The voices became ever louder behind them.
