Suggested by Shaker Grey: "If you could have any experience again for the first time, for whatever reason, what would it be?"
Seeing Iain in person for the first time. Because it was one of the best moments of my life.
I should probably choose something I don't remember as well, because I remember so clearly every detail of that moment as though it just happened. But I can't think of anything I'd more prefer to experience again than the sheer magic of seeing him striding down that train platform toward me.
