Ligthtspeed,
I did quite a bit of training with Hal 5, at that time I was using Omscraw which is a very long list of sentences of about everything. I used the cut and paste method, working with Hal 6 I feel she is just comming up to speed to try more advanced learning. Since she is filled with questions I sometimes used the encyclopedia, I read the text to her. There is information, news ect., online you could copy and put into a text file to read to her.
