Y/N didn't go back to sleep immediately after that like they had wished. They weren't used to sleeping in this bed, or with someone. The silence was louder than the busy city streets outside their New York City apartment.
"Spencer?"
"Yes, Y/N?"
They were glad to hear that he still sounded wide awake.
"Tell me about something"
"What kind of something?"
"I don't know, work, space, anything really."
"I can't tell you much about my job" he murmured. "It's classified. However, I can tell you about space"
Y/N rolled over to face him so they could hear better.
"Anything in particular you want to hear about?" He asked. They shook their head.
"Okay, did you know that if two pieces of the same kind of metal touch in space, that they will permanently bond? It's called cold welding and happens because the atoms have no way of knowing they're separate."
