Why Do We Not Speak Inbetween Washing Our Hands and Eating Bread?

In this clear video, Orthodox Rabbi Simon Harris of Wembley United Synagogue describes the halachic development of the custom of not speaking between the ritual hand-washing and eating bread. Rabbi Harris sites many of the different rabbinic sources in which this practice is discussed, rendering this video particularly interesting to those with a scholarly approach and some background in Jewish learning.
