     Freda Bright says," Only in opera do people die of love." It's true. You really can't love somebody to

death. I've known people to die from no love, but I've never known anyone to be loved to death. We just

can't love one another enough.

     A heart-warming story tells of a woman who finally decided to ask her boss for a raise in salary. All

day she felt nervous and late in the afternoon she summoned the courage to approach her employer. To

her delight, the boss agreed to the raise.

      The woman arrived home that evening to a beautiful table set with their best dishes. Candles were

softly glowing. Her husband had come home early and prepared a festival meal. She wondered if someone

from the office had tipped him off, or-did he just somehow know that she would not get turned down?

     She found him in the kitchen and told him the good news. They embraced and kissed, then sat down

to the wonderful meal. Next to her plate the woman found a beautifully lettered note. It read: "Congratulations,

darling! I knew you'd get the raise! These things will tell you how much I love you."

     Following the supper, her husband went into the kitchen to clean up. She noticed that a second card

had fallen from his pocket. Picking it off the floor, she read:" Don't worry about not getting the raise! You

deserve it anyway! These things will tell you how much I love you."

     Someone has said that the measure of love for his wife is love without measure. What this man feels for

his wife is total acceptance and love, whether she succeeds or fails. His love celebrates her victories and

soothes her wounds. He stands with her, no matter what life throws in their direction.

     Upon receiving the Nobel Peace Prize, Mother Teresa said, "What can you do to promote world peace?

Go home and love your family. And love your friends. Love them without measure."
