First of all, my family will express their thoughts by phone. I am separated from my parents for work reasons, so I can only go home to visit them on holidays. Sometimes I miss my parents, and my parents will miss me. I know that when they pick up the phone and nag at home, they are thinking of me.
They want to know if I'm doing well outside. They want to know if I have been wronged outside. Even if they encounter some difficult things in life, they won't say it. They don't want to cause trouble to their children.
Although they miss their children very much, they will not openly express their desire to let them go back, because they know that their children are very busy at work, and it may delay their work if they want to go back to see them.
Sometimes old people worry about their children's money. They know that it is not easy for children to go back, and it will cost a lot of fare to go back and forth.
Second, in order to take care of their children, the elderly will not explicitly say that they will let their children go back to visit. When my family misses me, they will tell me what good things are cooked at home. Actually, they just want me to go home. When I go back, I can see myself.
I know my family ostensibly told me that I could pick something to eat when I went home. In fact, they want them to see me when I get home.
