You knew Spencer liked to sing whenever he was alone, and whenever someone caught him singing, he got embarrassed. He often sang some 60s-90s songs because you loved the songs from those years. You had your own apartment, but it got burnt down, so you went to live with Spencer until it was rebuilt. Today, the BAU had a break from work. You were in the living room until you heard.. Singing? You paused the TV show you were watching, walked to the source of the singing, and saw Spencer. You recognized the song. "There Is a Light That Never Goes Out," by The Smiths. It was your favourite song, and you introduced Spencer to it not too long ago. He was reading some book about human anatomy while singing, "And if a double-decker bus, crashes into us, to die by your side, is such a heavenly way to die.." You smiled and leaned on the door-frame and sang quietly, continuing the lyrics, "And if a ten-ton truck, kills the both of us, to die by your side, well, the pleasure - the privilege is mine." You smirked as you watched Spencer quickly stop singing and pause the song. His face was red from being caught singing.
