Myself:
What are ‘baby’ ants? How do you know if they are baby???
Mother:
When the maid was cleaning your house in India, she saw patches of these ants. We went to investigate and then she told us that those ants only infest if the owner of the house is pregnant. It will go away when the baby is born, so it is bad to wash (kill) them.
Myself (giving my mother the “wadde!” look):
So, you did not wash those ants away? You leave the house to be infested with ants?!
