1.Today is Tom's 70th birthday,but there is anybody with him.He feels very disappointing.His sons didn't care for him on this special day.Although the cake is very delicious,but he doesn't want to touch them.He just wants his children come and see him.Nowadays,many young people are so busy and independent which they seldom visit their parents.But blood is thick than water.Our dear parents bring us up for a lot of difficulty.Thus,we should and must bring happy to them when they become old.
