Anyway, then I spent about an hour going through the xkcd archives instead of doing any real uni work but still couldn’t find the one I was thinking of (you know, the one where they drive out to the woods, and listen to the rain on the car roof? The alt text is something about playing fingertip games under a blanket…).
Sometimes I wonder why I actually write this stuff down…
EDIT: It’s ok! I found it! http://www.xkcd.com/283/
You must be so relieved.
