You know, it is probably true.
My overbearing ex MIL was staying with me and my Ex when DD1 was due. She kept trying to get me to take castor oil to get the baby out while she was there... I couldn't think of anything worse than having her there while I was in labour or even when I came home with bub.
Anyway, she left on Tuesday and I had DD1 on the Thursday. My MIL wasn't impressed! lol
