A discussion about a wire-bound A4 notebook, eg:
Colleague: I think i’ll run my notebook in widescreen mode from now on.
Colleague: I might be able to fit more on it.
Me: But the lines go the wrong way.
Colleague: Oh yeah. I should be able to right-click on it and choose orientation.
Me: Hmmm. *looks on internet* Oh, they do a version with 5mm squares!
Colleague: That would do it!
