It’s all Braille to me.
A teacher was looking for a folder she had misplaced that had some confidential information in it. Her e-mail said we couldn’t miss it (uh, obviously you can) because,"it’s written entirely in Braille." If I am the one to find it, then I’m pretty sure the information will stay confidential. That is, unless it’s about the floor of an elevator or the gender designated for a bathroom.
