Plunged from sky

Old man Yu was so scared that his loose bowels immediately reacted and a bad smell immediately filled the garden just as the vine wrapped itself around his mouth and pulled him up from the ground he was so panicky that he didn't even care about the yellow liquid dripping down his legs as he turned and twisted trying to make as much noise as he could but no one from the house came to rescue him, neither his wife nor her daughter, he was stunned. It was true that his mouth was covered and he could only muster muffle groans but the sounds were not small and the havoc he was causing wasn't silent either, this much din was enough for others to hear him right? So why didn't they come to save him?
