"Grass" is actually a poem that was written by Carl Sandburg. This is a poem in which he has published right after the World War I which is in the year 1918.

I was at lunch with my mother and we were discussing current events. We had placed our order about five minutes earlier. Just as we were beginning to become irritated our drinks were brought to us. My mother ordered a soda pop, where as I had ordered an iced tea. My tea was served with a slice of bitter lemon. After drinks, we had a wonderful lunch.
