an old man is sitting in the wheelchair,and a dog is serving him with milk and food.Ironically,it is the dog that takes the responsibility to attend the old man.We cannot help wonderinhg where the old man’s grown up children are.It is they not the dog who should take good care of their old father. The implied meaning of the picture is really provoking.It is quite true that in our society there are some grown-up children who treat their old parents badly.When their old parents are too old to take care of themselves,they often view them as a “burden” of their family life.They refuse either to support their aging parents financially or to look after them.No doubt,this immoral behavior of these grown-up children’s should be subject to social condemnation. To respect the old has long been a traditional virtue of the Chinese people. We should always bear in mind that we are much indebted to our parents in that they not only gave us life but have done much to bringing us up.It is against conscience to escape from the responsibility to take care of our parents.Rather, we should pay back for the love and care of our parents by making their later years happy and enjoyable.
