The social rules for dating change from one generation to the next.
There was a time when a proper young man and woman could not speak to each other unless they had been formally introduced. On the other hand, I understand from my patients that it is considered bad manners now for young people to date someone who has previously dated one of their friends.
The advertisements in The Village Voice were different than those in the various Jewish newspapers and different, also, from those in the New York Magazine.
Someone answering ads in one place might be replying to an invitation to engage in some sort of sex. Others were directed at more sober individuals who were thinking of getting married somewhere down the line.
If it were not permissible to date them in our turn, we would have had no one to date.The women reported to me that they did not feel threatened—although they were very likely to report that they felt disappointed. Most of the precautions I thought were important were against being stuck for a whole evening with a boring date.I especially recommended arranging to meet for the first time only for coffee or a drink.Women made the trip west with the expectation that they would marry and be happy-- more or less.And it turned out they did and were, although there is never very much evidence about whether or not a particular married couple is really happy.
