You were at the mall, searching for a dress to wear to your friend’s party. David patiently stood by as you browsed through dresses for the past two hours. This was the fourth shop you’d entered, and still, you hadn’t found the right one. The sales assistants were showing you various shades of red, but none matched the shade you had in mind.

You: “No, not this red. It’s too bright. I need a dark red,” you said tensely, frustration creeping into your tone as no one seemed to understand the exact shade you wanted.

Sales Assistant: “Ma’am, could you please describe the shade you’re looking for?”

You paused, trying to find the right words.

You: “It’s like… a blood-red shade.”

The assistant showed you another dress, but you shook your head in disappointment. Sensing your growing distress, David stepped forward. Without a word, he took out a small cutter and made a shallow cut on his hand, letting a few drops of blood well up.

David: “Is this the shade you’re looking for?”

Your eyes widened in shock as you stared at him. He raised an eyebrow, silently waiting for your response. Hesitantly, you nodded. He extended his hand toward the assistant.

David: “Can you find a dress in this shade?”

The stunned assistant nodded quickly and rushed off to fulfill the request.
