Cover art for Vapour Trail lyrics by Trespassers William

For me, this song is about letting go. About someone who would mean so much, yet it does not work as one would want it to.

I love the way feelings are depicted in the song ("Tremble with a sigh").

Also, the concept of the title can be related to the marks this affair leaves; amidst a perfect blue sky, there's this vapour trail that makes it perfectly unperfect.
