Not all of us have had to experience this, and that is a good thing. However, some of us have family who have to go to war, or have gone to war. For some families, those brave soldiers don’t come back, and they don’t forget this.
Did you ever have to explain to a son, or daughter, or niece or nephew why that soldier had to go away? They don’t understand war, or the politics that leads to it. For them, you have to make a unique explanation. This daughter needed an explanation, and she got one thanks to a patient, understanding, grandfather.
