There are some things you can never forget.

They stick in the back of your mind, like fungi to a tree. When you least expect it, that fungus will send its spores out, filling your head to the brim with those traumatic memories that have been festering in your subconscious, and forcing you to relive every single horrible moment.

I'll never forget what I saw that day.

And I'll never forget how it smelled, either.
