Hush hush, say no more!

The Khavinski family are again featured on this card, dated April 17th, 1962.

Hello and greetings to Ilya! (this seems to be a female name)

I'm in a hurry to write to you to let you know about a small change in plans. I will probably spend the Seder night (= Passover eve) at Korazim, so I will only be back Thursday noon. If it's not too much trouble, and I hope it's not, please call me in the afternoon around 4-5pm, and then I'll probably be home and will also be able to tell you about the Seder events.
Otherwise there's nothing new. I have a small piece of news, but this space is too small to contain it. Therefore I bid you farewell and wish you a happy holiday.

From Shmulik.

I wonder what that small piece of news was. Maybe Shmulik proved Fermat's theorem?
