It can be difficult to use speech recognition software. This is especially true since most people in my house seem to think that because I keep my door open most of the time they are automatically issued an invitation to enter. The truth is I keep my door open most of the time because I can’t all when it from a closed position very easily. Sometimes they knock but refuse to wait for permission to enter before they have crossed the threshold. I wonder whether they would respect the kind of light you find outside of a photographer’s darkroom , if the light is on do not enter. I somehow doubt that even that would work, oh well . Good night John boy.
