Sunday in the park (summary)

In the article by Bel Kaufman "Sunday in the Park", the author talked about two families who were arguing just because of one child threw a spade of sand at the second child. Morton, the mother of the second child felt very unconfortable with the situation, but she didn't react until her husband step in, and the father of the obese child told his son that it was ok to continue throwing the sand if he wanted to because they were at a public park. When Morton heard that she decided to leave the park, because she felt that fighting wouldn't resolved anything.
