could samwise gamgee have been lying?

Never thought this before, but now I wonder...

In "The Fellowship of the Ring," the Fellowship had just met Galadriel and were asking each other what they thought/felt when she held each one of them in her gaze:

"What did you blush for, Sam?" said Pippin....
...answered Sam, in no mood for jest. "If you want to know, I felt as if I hadn't got nothing on, and I didn't like it. She seemed to be looking inside me and asking me what I would do if she gave me the chance of flying back home to the Shire to a nice little hole with --- with a bit of garden of my own."

With a bit of garden? Or was it really Rosie Cotton? :)
