His sons who are busy working don't care for him on his special day.2 the cake is very delicious, he doesn't want to touch it. He just3 his children to come and stay with him. Nowadays, many people are so busy that they4 visit their parents. However, blood is5 thicker than water. Our dear parents make every effort to bring us up, so we are supposed to treat them well when they become old.
