I think Q rescheduled it so he can do it spontaneously. That way it keeps out the normies who haven't a clue and, since the normies won't be on the board then, it will likely bring questions from autists who have some idea what they're talking about. Normies are posting questions they'd like to ask in one FB group I'm in. Let's just hope they don't fill up the bread with that kind of garbage. Acting like Q is their private fortune teller or something.
Unless…he did it because of this scenario. Envision this: Q sitting all comfy in a nice armchair in his study, perusing the board on his phone. His wife sticks her head in and says, "Dear, did you remember tomorrow we're going to the neighbor's BBQ?" He rolls his eyes, mutters under his breath, thanks her for reminding him, then goes back to his phone to make the post. (I think my first thought is probably more likely, but the second one makes me smile.)
