【正确答案】Dear Xiao Jiang,
Do not be over-concerned that young girls take too much interest in their looks. It is only natural that young ladies want to look fashionable. I know Mingming is not the kind of girls who are extravagant or vain. As long as she does not always expect you to pay for her, there is nothing to worry about. Once you are married and have a child to look after, she will willingly give up buying expensive clothes for herself. Now you should feel lucky that she does not always drag you along shopping with her!
