At age of 83, granddad went to hospital for the first time. "What is this?" he asked as he held up the bell cord they had fastened to his pillow.

"That's the bell, Granddad." I replied.

 He pulled it several times, then remarked, "I don't hear it ringing."

 "Oh, it doesn't ring," I explained. "It turns on a light in the hall for the nurse."

 "Well!" he replied indignantly. "If the nurse wants a light on in the hall, she can turn it on herself."

爷爷在83岁的时候，第一次住进了医院。“这是干什么用的？”他抓起系在枕头旁边的呼叫铃的绳子问道。

“那是拉铃用的，爷爷。”我回答说。

他拉了几下问：“我怎么听不到铃响呀？”

“哦，不是它响，”我解释道，“你一拉这根绳子，护士值班室的灯就亮了。”

“原来如此！”他愤怒地说，“如果护士想开灯的话，她完全可以自己动手嘛。”
