Borges.........two hours for questions?
Recently I was one of a hundred participants invited to discuss my profession at our High School's career day event................ after my presentation we had 20 minutes for questions. I averaged two to three questions per session and found it impossible to fill all of the twenty minutes allotted. This was common with the other speakers I had a chance to talk to afterward.
With that in mind you may want to prepare some additional material aimed at generating a lively question and answer segment.
I think it's great you are doing this............ l et us know how it went.
