One possible version:
It is the old man’s birthday today. Now he is sitting on a sofa alone. Maybe his wife has been dead. On the right side is a big birthday cake sent by his son. And there are also some presents given by his daughter on the left. Yet the old man doesn’t feel happy. Instead, he looks very sad because he is lonely.
Our life is getting better and better than before. Some people think that old people will be satisfied as long as they have enough to eat and drink. I think they are quite wrong. Old people easily get lonely because they have no work to do. So we should spend as much time together with them as we can and take care of them in every possible way.
