NCB, That is so ridiculous that the MIL reacted like that, but somehow I believe if you hadn't sent flowers then you would have been accused of being thoughtless. The way I see it in this situation is "You're damned if you do,and damned if you don't". So don't pay any heed to them, you know that you did the right thing. You were thoughtful and caring.
Life's challenges are not supposed to paralyze you, they're supposed to help you discover who you are. -- Bernice Johnson Reagon
