"Sirius?"

"Yeah, Rem."

"Did you ever feel like you don't exist? Like you're a phantom: awake, aware, but invisible to anyone around you."

Sirius sits up, followed by Remus a moment later. "Occasionally. You?"

"All the time." He looks away. "It's like the only way I prove to myself I exist is by seeing someone see me."

Silence reigns as Sirius contemplates his response. He places his hand and Remus' jawbone and his forehead against his.

"Proof enough?"

"More."

Gently, but with definite vigor, he places his lips on Remus'. "And now?"

"I remember."

Sirius made sure he never forgot.
