Katherine was a professional tour guide. As she spoke, she led the tourists through the gate toward the main hall and made sure no one got left behind.
As they were making their way, an elderly couple suddenly said that they could not walk any further and that they wanted to sit down and have a rest.
Katherine walked over, "Oh dear, we've only been walking for about ten minutes. Could you try for a little longer? The front is fascinating."
The old lady smiled bitterly, "We are old and not as strong as the young. My husband… He is weak. The doctor had advised him to stay in the hospital, but he felt that if he didn't travel now, he might not have another chance in his lifetime."
Sophia noticed that the old man's face was ashen and waxy. It was clear he was very ill.
"Let's give them a rest. The old man is really out of strength." Sophia told Katherine.
