I don’t remember where I got this one from, but it came back to me today when someone at work was talking about how their father likes to “play” with settings (VCR, TV, Air Conditioning, etc) and cables, then deny all knowledge.

There’s these three people: One IT Helpdesk staff member, One Software Developer, and one User.

They’re each put in a separate room, each room has a table, chair, and a window. On the table is a glass ball.

24 hours later, when checked – the IT Helpdesk person is sitting there, waiting for someone to ask for help. Similarly, the Software Developer is waiting to be given a task.   The User, however is sitting in the corner – there’s no glass ball, and the window is broken. “What happened?”, they’re asked. “I don’t know, it just happened”
