Paper

I think I've already mentioned this, but the standard paper size is called A4, and measures 21 cm by 30 cm, or 8.3" by 11.7". The hole-punched variety have two holes, roughly 1/3 of the way down the page. I've gotten used to it, but during my revision I brought out some notes on US Letter and I forgot that many people had never seen it. It was "so short!" and had "too many holes!" Hah.

I learned that the equivalent of the "nuclear family" is known as the "A4 family".

"So.. if you don't have A4 paper, then what do you call the A4 family?"
"The what?"
