This Shabbat, we'll start reading a new Book . Vayikra.
The Book starts with he word "Vayikra" = and [HE] called Moshe and spoke with him.
Maybe this teaches us that when we want to start communicating with another person we have to establish an atmosphere of "listening" and this can only happening if we are listening to our partner. We cannot expect anybody to listen to us, if we don't listen. I guess this happens between individuals as well as between groups or nations.
