While Andrew was getting ready for work one Friday morning, he announced to his wife that he had finally decided to ask his boss for a salary raise. All day Andrew felt nervous and anxious as he thought about the upcoming showdown. What if Mr Larchmont refused to grant his request? Andrew had worked so hard in the last 18 months and landed some great accounts for Braer and Hopkins Advertising Agency. Of course, he deserved a wage increase.

The thought of walking into Larchmont’s office left Andrew weak in the knees. Late in the afternoon he was finally courageous enough to approach his superior. To his delight and surprise, the ever-frugal（一向节俭的）Harvey Larchmont agreed to give Andrew a raise!

Andrew arrived home that evening—despite breaking all city and state speed limits—to a beautiful table set with their best china, and candles lit. His wife, Tina, had prepared a delicate meal including his favorite dishes. Immediately he figured someone from the office had tipped her off!

Next to his plate Andrew found a beautiful lettered note. It was from his wife. It read: “Congratulations, my love! I knew you’d get the raise! I prepared this dinner to show just how much I love you. I am so proud of your accomplishments!” He read it and stopped to reflect on how sensitive and caring Tina was.

After dinner, Andrew was on his way to the kitchen to get dessert when he observed that a second card had slipped out of Tina’s pocket onto the floor. He bent forward to pick it up. It read: “Don’t worry about not getting the raise! You do deserve one! You are a wonderful provider and I prepared this dinner to show you just how much I love you even though you did not get the increase.”

Suddenly tears swelled in Andrew’s eyes. Total acceptance! Tina’s support for him was not conditional upon his success at work.

The fear of rejection is often softened and we can undergo almost any setback or rejection when we know someone loves us regardless of our success or failure.
