“This house has no bells,” he said in a nasal voice; “it has a tendency to discourage one.”

“I would be glad to speak a few words to your sister, if it is your sister that I want.”

“Tea? Excuse me! I don't drink tea.”

“There is also coffee,” Greta said.

The stranger's progress towards the arbour was so slow that Greta arrived considerably before him.
