What’s a mystery from my own life that I’ve never solved?

Myself.

I can’t explain why I think the way I do, why I act the way I do, why I feel the way I do, why I change the way I do. I can’t explain why certain songs seem to evoke mood swings in me or how thinking about certain subjects such as Kirby can uplift my spirits. I can’t explain why I occasionally behave so irrationally over the silliest things and say things I know are harming toward others, and I definitely can’t explain how I am so the clutter type and yet suddenly one day get into an obsessive cleaning mood!

Myself is indeed a mystery
That will likely never be solved
You are to you as I am to me
Forever this myst’ry will be unresolved.
