Calum would hand you this mixtape the second before leaving to get on a plane to a whole different country. You two would be hugging and his hands would rub your back and he'd quickly grab a CD out of his bag. His eyes would glow under the harsh lights because of the oncoming tears. He'd probably attempt a smile while handing you the disc. On it read "For when you miss me.." sloppily written in sharpie.
