“Hobbits always so polite, yes! O nice hobbits! Smeagol brings them up secret ways that nobody else could find. Tired he is, thirsty he is, yes thirsty; and he guides them and he searches for paths, and they saw sneak, sneak. Very nice friends, O yes my precious, very nice."
Sam felt a little remorseful, but not yet trustful.
"Sorry," he said. "I'm sorry, but you startled me out of my sleep. And I shouldn't have been sleeping, and that made me sharp. But Mr. Frodo, he's that tired, I asked him to have a wink; and well, that's how it is. Sorry. But where HAVE you been to?"
"Sneaking," said Gollum, and the green glint did not leave his eyes.

...

"Hullo, Smeagol!" Frodo said. "Found any food? Have you had any rest?"
"No food, no rest, nothing for Smeagol," said Gollum. "He's a sneak."
"Don't take names to yourself, Smeagol," Frodo said. "It's unwise, whether they are true or false."
"Smeagol has to take what's given to him," answered Gollum. "He was given that name by kind Master Samwise, the hobbit that knows so much.”
