Why might it be important that Nakhmen state that his nephew, Lemml, has never seen a play?

It is important for Nakhmen to say that his nephew has never seen a play, because it helps to explain his reactions during the reading. Lemml is quickly drawn in by the plot, unlike the other men who are turned off at the start by the brothel setting, as it is stated that many plays at that time were taking place in brothels. This statement also shows that he is from out of town and uncultured in the eyes of these men.
