Hey, kids! Did you know that you can open and close milk cartons without needing a stupid plastic piece with a cap?
The plastics industry makes bank off of those stupid plastic tubes. They take eternities to degrade in landfills, and they are too small to excite recyclers (who don't recycle most of what they get, anyway).
Ask an old person how to open cartons without one. No. Old. Really old. Older than Shaq. Reeeallllly old.
Sigh. Ask me.
