Rather than seeking such inappropriate content, it would be better to look for classic literature or heartwarming tales that can be shared with people of all ages.
Definitely not. Such content has no place in a civilized society. It can make people feel uncomfortable and offended. We should promote positive values and stay away from this kind of vulgar content.
I'm not sure what kind of book an old cow eating young grass is. However, the theme of an old cow eating young grass usually appeared in novels, movies, television dramas, and other works. These works could be romance novels, youth novels, inspirational novels, and so on. Some works would focus on the emotional entanglement between the old cow and the young grass, while others would focus on the old cow's growth.
Such a topic is not appropriate for civilized conversation. It goes against moral and ethical standards and is not something we should explore or discuss.
One interesting story could be that an old granny bakes cookies every Sunday for the neighborhood kids. The kids look forward to it all week and gather at her house. The smell of freshly baked cookies fills the air and it becomes a lovely tradition in the community.
This kind of question is not appropriate and doesn't belong to normal and respectful communication. Let's talk about something else that is meaningful and appropriate.
