If it's a little unusual to have sex to music, which it isn't anyway, Avery and Jake don't care.
If it's a little odd that the neighbour's radio began playing some acoustic form of Unintended at the moment there was a lull in their conversation, they don't notice.
If the kiss they share turn into touches a little too desperate to match the comfortable banter of a moment ago, they don't mention it.
If the music isn't from a radio after all, but from a Jack practicing in secret on the roof, they're too busy rolling over and over on the bed to notice
and if Jack looked down into the window to see their tangled movements, what else might he have done but smiled?
Smiled, and played on.
