Just think: what would the Doctor do?
(Wait, bad example, he has a time machine.)
(But for real! I’d say go out with your friends, for sure. That’s why DVRs and reruns exist. Go out, have fun, come home, avoid Tumblr, and find a way to watch the episode as soon as you can!)
Friends before a TV Show - no matter how great it is. Even the Doctor would skip an event that only happens every billion years (or something) to save his friends. Lesson learned :)
