The Lost 'D': Unexpected Results

My regular readers (reader?) will know that I have recently turned a campaigner for Lost 'D's. (Read here first to understand the story thus far)

In my cafeteria, there is one such sign. It reads "Close". Just the other day, I informed the office boy (who deals with such matters) that indeed "Close" is completely incorrect and can lead to infections diseases. I explained at length what my Grade 4 grammar teacher had taught me.

And lo! By lunchtime, the sign had been corrected! It now said "Closed"! Joyously I whistled to myself and did not get bummed that (as always) in my hunger, I had turned up at the cafeteria an hour too early.

But that's not all: With great understanding comes great responsibility! This enthusiastic guy, he actually corrected such signs all over the office! Everywhere I looked, "Closed" signs looked back at me, and I was satisfied that I had helped the world become a better place.

I walked towards the stairwell and passed a door. I paused to read the sign:

"Please closed the door after entering."

Kindergarten grammar lessons flashed in my head. I just walked away from the abomination, took long calming breaths and tried to get a grip on my understanding of the world.
