The song describes someone waking alone after a relationship has ended. At first, the speaker cannot decide who was at fault and suggests that perhaps nobody was. Ordinary habits remain, though: the speaker still thinks of the other person and almost greets them as if they had returned. As the song develops, sadness becomes mixed with acceptance, but the wish to begin again does not disappear.

The empty room and solitary morning make the separation feel immediate and quiet. The familiar greeting that slips out by mistake shows how deeply the old routine remains in the speaker’s mind. The image of dust gathering on once-bright days suggests that even happy memories can fade or become less vivid with time. The lyrics also describe the couple as gradually drifting out of step, rather than pointing to one dramatic cause.

The repeated word “probably” matters: the speaker is trying to explain the breakup, but does not sound fully certain. Calling it an ordinary love story may be a way to make the pain seem manageable, not proof that the relationship was unimportant. The lyrics accept that people cannot understand or forgive everything, and that a once-kind relationship may become painful. Still, the final imagined return leaves room for regret and longing. The ending’s small smile could suggest tenderness, resignation, or both.
