Hmm, well in that case, you have to think, stuff what she tells everyone else, you are about to have a baby and you want to go out for
lunch. End of.
You feel like getting out of the house.
You would like to eat out while you get the chance as it will be harder with the baby.
You don't want to tidy up or ask her to to tidy
up, it will be easier to go to a cafe.
Can you afford to buy her lunch? Extra tactics there, I woule like to buy you lunch mother...
