Part 4!
About
Rem It was a long time ago. I'm only just remembering it now. Reaching out into the darkness is just an exercise in futility. Beside a kind person like you, I'm sure it's not me, but someone else who truly belongs. Lately, you know, I've been having nothing but bad dreams. A vague pain tightens in my chest. The words I swallowed while thinking of you, they're so dear to me I can't help it. Please, just smile. I'm sure I'll remember today's events from here on out, and I'll probably fall asleep clutching my own ugliness. Beside a righteous person like you, I'm sure it's not me, but someone else who truly belongs. Even though I know that... Lately, you know, I've been having nothing but bad dreams. A vague pain tightens in my chest. The words I swallowed while thinking of you, they're so dear to me I can't help it. Please, just smile. About you | About you I wish I could have understood you, even just a little. Even my heart, wounded as it counts up empty platitudes, is so dear to me I can't help it. Please, just smile.
