#7: Flush Twice
You know who wants to see what you just did in the bathroom? Absolutely no one! Unfortunately, double flushing doesn’t seem to be a commonplace practice. It is one of the world’s biggest unwritten rules, though. And one Reddit user felt the need to point it out.
Although not expressed delicately, the post gets the point across. What happens during toilet time should remain a secret between you and the porcelain throne. Please do the world a favor, and “double flush if you must.” You’ll be practicing such a simple act of decency, and humanity will silently thank you.
