I posted back in July about an embarrassing moment which was entirely my own fault. I’ve discovered (via a casual google) that the woman to whom I asked my tactless question is about to take maternity leave.
So in fact she probably was pregnant in July. But perhaps didn’t know, or wasn’t sure, or hadn’t told her husband yet, and in any case was too early on for it to really have been showing, and anyway there are perfectly understandable reasons (though it would have been uncharacteristic of her) why she would have enjoyed winding me up.
Oh well. I shall stand by for further news, and not ask any more questions.
