Surely, this other lady realizes you had plans for your "special" friend and would not expect anything as "nice" as what you give her friend.  Does this make sense? lol  Say, if you give your "special" friend roses and a nice gift, then give this other lady some beautiful carnations and a box of candy.  Candy is always safe.  Roses are for special people.  Good luck!  You know how women can be!

  Just saying.
