There is a great Chinese saying that goes as: a tree wants to be quiet, but the wind still blows it; a son wants to support his parents, but his parents have passed away. It tells us that we usually expect to do something but once we have the ability to do it, we have lost the chance to do it and we can only have regrets. When I look around, some of my friends are from only-child families. When they work hard every day to support their family and take care of their children, they seldom have extra time to look after their parents. In that case, though they really want to repay the kindness of their parents, they lack the time and energy to do it. The only thing they can do is to hope that their parents keep healthy. But the things happen after are usually out of their control. As people get older, they usually become weaker and easily get sick. They need to be cared for by others, if they can't rely on their children, maybe nursing homes is the only choice. According to my experience, most of the nursing homes are amazing. Elder people can do many activities with others over there such as singing and dancing together and food is also great!
