He would change his voice for each character, the scariest (and most fun) was Jacob Marley's haunting voice, and his most gentle was reserved for Tiny Tim.

Mware, your father sounds like my kind of dad - mine read to us every night after dinner. There were classics like The Swiss Family Robinson, Treasure Island and the like, and lots of science fiction - mostly Asimov. He started when we were in elementary school and continued until he died when I was in my mid teens. A cherished memory indeed! And my brother and I are still both avid readers to this day.
