Two objects cannot occupy the same space at the same time. That’s what our high school physics teacher taught us. I know that, you know that.
So if I scheduled a whole day workshop in the conference room first from 10:00 a.m. to 5:00 p.m., why would you schedule a meeting there from 2:00 p.m. to 4:00 p.m.? Were you absent when your teacher taught you this, or were you just not paying attention?
