I think we should be able to ask who is at the door before opening it, I
remember, and that could be a first for me, remembering that is, there
used
to be gadgets you put outside with a speaker and a microphone in, so if
someone rang the bell you could ask who it was before opening the door,
but
I have no idea where one would go for such a gadget.
So, which store do I ask at first?
