So my parents were at this meeting were they should watch a video, person one wanted to play the video from his computer but guess what happened:

Person one has windows on his computer. Windows wants to update. Person one clicks on update in three days.
Windows be like 🖕I'll start updating now.

Person two decides to play the video on his computer instead.
He has windows too. It could've worked fine, but a cable is missing or something.

Person three has a MacBook. Person three tries to play the video. It could've worked fine but he doesn't know how to enable subtitles and without them they cannot watch it.

So they ended up watching the video a day later after the computer of person one had updated itself.
