B
I have two children and I make them do housework. However, my mother-in-law (婆婆) doesn’t agree with me.
She thinks I’m too harsh. In her opinion,it is adults’job to do housework.
My family is made up of four family members. No one in the family is more important than another, so each
member should help with chores. I don’t ask my children to do the samechores, because their ages are different.
At the end of the day, after they finish playing with their toys, I ask them to put the toys away. If they don’t,
they will have to say goodbye to their toys. I expect my children to sweepthe floor, set the table and help fold their
own clothes. I don’t think I’m asking too much. I know they are tired after a long day’s study at school, but that’slife—harsh but real. I don’twant to pay them for doing some chores. They live in the house, so they should help out
with some things in the house. No one is going to pay them for cleaning up their rooms later in life and I’m not about
to start doing it now.
Some parents protect their children too much from anything unpleasant (使人不愉快的) and make their
children’s lives too comfortable and safe, but I’m not interested in that way. I hope my children are able tolook after
themselves and can be independent early.
