The definition of a good child differs between societies and cultures, but in my country an obedient and kind person would be considered as a good son or daughter.
Good opening :)
The definition of a good child differs between cultures. However, in my culture, obedience and kindness are considered be the mandatory qualities of a good son or daughter. .... I tried align that line more with the prompt.
Parents always expect their children to obey them. No matterno matter how old they are.
.... you need to combine the two sentences.
They cannot bear their children's disobedience even if theytheir children are married.
.... here there is a confusion as to whom you refer by "they" (parents or children). That's reason why I made that suggestion.
I think nowadays children in most countries do not obey their parents like their ancestors
... this idea comes bit rigidly without having a good connection with the previous line. Set up a sound line.
However, now it can be seen that younger generation is drifting away from this cultural norm. They, like the children in most of other countries, do not really care about what their elders feel and wish to be independent in making their decisions.
