There is nothing wrong if we help the ladies in the house in domestic works. Based on our time and convenience we should share their responsibilities. My elder son will cook food on Saturday and Sunday evenings. We all will be doing some help to him in completing the works.
I agree with the author that it is quite commonly seen in almost every home that men don't lift plates. This is the common tradition. There is nothing wrong in helping ladies when men are at home and especially these works which they can easily do.
Our family eat together. We don't eat in separate plates, rather we take food in same plate, Even in large plate 4 to 5 family members can eat together in the same plate. So there is no such issue for us which the author has raised about.
