"The way I see it, every life is a pile of good things and bad things. The good things don't always soften the bad things; but vice-versa the bad things don't necessarily spoil the good things and make them unimportant."
This is def one of my favourite Doctor Who episodes.
Taken from all over the goddamn place: When you see this post, quote Doctor Who in an lj entry.
The Doctor: Don't argue with me! Peri: I will! I'm not letting a manic depressive paranoid personality like you tell me what to do! The Doctor: Manic depressive?! ME?! (The Twin Dilemma)
