"And, of course, they've always condemned dancing. You know, you might touch a member of the opposite sex. And you might get excited and you might do something natural"

This quote by Frank McCourt is a commentary on the conventional worths of society. He is mentioning that dancing has actually often been condemned by society, as it can cause physical contact in between members of the opposite sex. This physical contact can result in excitement and a natural reaction, which is viewed as inappropriate by some. McCourt is recommending that this is an out-of-date view, which dancing ought to be seen as a natural and satisfying activity. He is likewise suggesting that society must be more accepting of physical contact between members of the opposite sex, as it is a natural response. This quote is a suggestion that conventional worths ought to not be blindly followed, and that society needs to be more open-minded and accepting of various activities and behaviours.
