One morning, Sam went to school by bus. It was a long way, so he wore a Bluetooth earphone(蓝牙耳机) to listen to music.
Suddenly, an old woman went up to him and said quietly, “Good morning, sir!” He was surprised but asked in a friendly way, “What’s up, Madam?”
The old woman didn’t answer him. But she looked happy and turned to an old man next to her and said loudly, “You see. His audiphones (助听器) must be pretty great. I said in a quiet voice, but he could still hear me.”
