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 a 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 festive
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, t
hen 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(值得) it anyway! These things will tell you how
much I love you."
Someone has said that the measure of love is when you love without meas
ure. What
this man feels for his wife is total acceptance and love, whether she succeeds or fails. His
love celebrates her victories and comforts 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.
