I'm a teacher at an Academy. I set my students the task of writing a history essay on a year BCE. One of my students, instead of giving me his year, gave me this slip of paper before walking out the room:
Hi, I am no longer needed at your academy. you're probably thinking 'He? well, 'E actually isn't needed'. and "'E" isn't needed, that isn't a Lie. i'm a humble Bea, A can be done without. No complaints, O time to leave. my Mug won't be seen with You anymore. oh, and my friend Ale, 'E isn't needed here either. like the number Pi when calculating one plus one, I am not needed. So my big O won't utter sound here again and shall be removed. Are, my other friend, 'E can go too. Cue for 'E and to disappear. take A away from our Bar. Rob, O no more left. Pod, O without it. A in our Pad isn't needed. Age is a 'E beyond his expiring date. i want a Cod, but i'm allergic to fish with O in their name. i'll just go Sob in a corner - O you've left. time for Tea, A can be done without.
On the back of the paper appeared to be half the periodic table:
Which year BCE is my student doing his project on, or has he left forever?
