"Have you tried sex/curry/pineapple?" Oh! No! I've never heard of those things! I can't read you see, so haven't actually bothered to look up online if there are any natural ways of inducing labour, because I really enjoy looking and feeling like an elephant with weight issues.
"Are you still here?" Erm, evidently yes.
"Haven't you had that baby yet?" Evidently not.
Also do not to a comedy double take when you see that the bump is still in place.

Acceptable things to say include "would you like a cup of tea?" and "Good morning!" You know, like you would say to a normal human being, rather than a bump on legs.
