I suppose pregnant women do get tired of each person they talk
  to only discussing either babies or pregnancy with them.  I was at a
  party one time and overheard a lady ask an obviously near full term
  mother-to-be how she was feeling these days.
    The expectant lil' Mother frowned and said, "Not too good.  I've
  missed seven or eight periods, and I'm beginning to worry about it."
