Vapour Trail

The lyrics describe someone watching a loved person who seems vivid and close one moment, then distant or absent the next. The speaker expresses devotion despite this uncertainty: even when the person fades or is hard to understand, the speaker still loves them. The mood is tender and dreamy, but it also carries frustration about how little time they have together.

The “vapour trail in a deep blue sky” suggests something beautiful that appears briefly and then disappears. The sun that “blind[s]” the speaker may imply that love is so powerful or dazzling that it makes clear judgment difficult. “Thirsty for your smile” is an expressive way to say the speaker longs for the other person’s warmth and attention.

The lines about never knowing whether the person will “come and go” leave their situation unclear. They may be physically separated, emotionally unpredictable, or simply difficult to hold onto. The final lines suggest that time belongs to both people, yet they cannot find enough of it to express their love fully. This could describe a troubled relationship, but the lyrics do not explain why the time is limited or why the beloved fades away.
