We are talking computers with our friends, one of who is desperately computer-illiterate. Let’s just call her A (because her name starts with ‘A’. How diabolically clever of me!)

Adam (bragging): You’ve got to get yours set up with a water cooling system.

A: Huh?

Adam: Water cooling. So there’s no need for fans.

A: What?

Adam: It makes the computer quieter.

A: So where does the water come out?

Adam (confused): It…like…doesn’t…

Karen (cottoning on to where the language was failing the communication process): A, the water cooling he’s talking about isn’t the kind you drink from.

We all sigh in relief.
