I was a little surprised and told the man that or he was a little early or far too late, but for New Year wishes he should wait for the first January next year. There was a pause and then : "Is this not Madame X ?" No, I answered, I think you dialed the wrong number ! He excused himself and explained that it was the Jewish New Year ! I thanked him for his good wishes and wished him also a happy prosperous New Year ! Then we said good bye.
Afterwards I googled for the Jewish New Year and learned that it had been on 14 et 15 September and that it was now the year 5776. Now I wonder how old I am ??
