Positive or Negative?

My friend confessed to me the other night that she has put on a few pounds. Being a girl and prone to over analysing things, the thought crossed her mind, that maybe the extra pounds were not the result of a few too many packets of Percy pigs, but in fact the result of being with child. Once this seed had been planted she became so concerned (and sleep deprived), that she had to buy a pregnancy test to just make sure. The results were negative.

It just read: not pregnant, just fat. Seems the only baby she is having is a food baby.
