Madge Arwell : Listen Cyril, tell him that I've borrowed Mr Goldsmith's car, that I've found a spaceman in a field, possibly an angel, but he's injured and I can't get his helmet off, so I'm going to have to take him into town to find a police telephone box. All right?
Cyril Arwell : [thinks] All right.
Madge Arwell : Good boy.
[She exits. Cyril's father enters through another door]
Reg Arwell : Was that your mother? Where's she going?
Cyril Arwell : Out.

Madge Arwell : Oh. Do you want me to do it with a pin? I'm good with a pin.

Of course when the Christmas period is over I shall... I don't know why I keep shouting at them.
The Doctor : Because every time you see them happy you remember how sad they're going to be. And it breaks your heart. Because what's the point in them being happy now if they're going to be sad later? The answer is, of course, because they are going to be sad later.
