Office Supplies for All
Here’s someone confirming what I said earlier, that most offices have a place where you can get your hands on office supplies, so that you can use them while you work. As long as that closet is stocked, you should never have to run out of pens or pencils at work.
So if you’re a teacher, here’s a tip: don’t tell people they need to remember a pencil because they’ll have to remember their own pencils once they’re out in the real world. That might not be true. Just tell them that they need to remember their pencils because otherwise, they can’t participate in your class.
