Nerdy observation from someone who works in edtech:
It is no longer okay to not know how to hook your computer up to the projector. Are you using a computer? Does it need to be hooked up to a projector? Then you need to learn how to do that.
I tried giving him the benefit of the doubt. Maybe the laptop VGA connection is missing or hidden. Maybe he’s not wise enough to know he can unhook the VGA cable from that doc camera, or even the computer in the workstation to his left (and use that for his laptop instead). Maybe he forgot the dongle he needs to hook up his Mac. But if none of those things are true, then this type of nonsense is just not okay.
