JM+dinner's+point+of+view.

What the author is telling us is that although there are some foods that we love and enjoy eating, if you think about it from the point of view from the animal being consumed, it is not such a great feeling. Many people take for granted the food that is in front of them and put zero thought into how the food got there. Animals go through cruelty to be on a dinner plate and many people are unaware of that.

Good job, Jonathan. Shel Silverstein has a way of making a point very easily, with few words and a bit of humor. You've identified his central message and explained it well.
