It hadn't occurred to her that he had forgotten her birthday until she arrived at work the next evening and found an envelope on her desk. She recognised the handwriting instantly and smiled to herself.
Picking it up, she slid a finger under the seal, then gently slipped the card from the envelope - revealing a picture of several delicious looking cakes.
Inside, it said, "I didn't forget. I'm just late. Usual place. Usual time. My treat."
Her smile widened. A glance at the envelope confirmed the card had been hand delivered. He was in Vegas: Best birthday present ever.
