My son asked if he could use the printer today. I said of course he could, as long as he printed double sided. “Why?” he said.
“If you print double sided you use half the paper. Half the paper means you only need half the ring binders to store it in, half the shelf space so half the wall space.”
“I’m only printing four sides.”
“Every little helps!”
I’m not sure he was happy with my reply.
