You're on a crashing plane and your partner is fast asleep. Would you wake her/him up to say 'I love you' one last time or let her/him die in her/his sleep?
Honestly, I'm not sure. Sarah always says that I tell her I love her way too often anyway. But I'm inclined to say I'd wake her purely for practical reasons - we stand a better chance of escaping from the 'plane once it's crashed if we're both awake.
