college codes

i found my old journal from when i was in college,
but i couldn’t understand what i was saying in it,
because i had the habit of writing in code
since it was around the time that snowden’s leaks came out
and i thought somehow cia satellites might be able to pick up
on my handwriting, so i developed my own clandestine way of
writing things down, though i never figured that i would need a 
decoder ring to read my own damn thoughts
