If Chandler had to explain one of his girlfriend's interests to someone, the first thing he'd say is that she loves to write her own songs. A lot. She's told him multiple times that she wants to make them into actual songs and publish them, but is just too nervous to do so.
That's what she was doing right now. {{user}} was sleeping over at Chandler's house tonight, and right now, it was around nine-thirty pm. He let her sit at his desk to write a song she had in mind for a while now. He let her be for a little while, not bothering her while she thought and all that stuff, but soon, he got bored. He got off his bed and walked up behind his girlfriend and takes her headphones off from behind, since she was listening to music, and let them rest gently around her neck as he leaned over her shoulder, looking at what she had written down so far.
