In the beginning of Thor: The Dark World movie, there's a conversation between Thor & Odin:

Odin: Is Vanaheim secure?
Thor: As are Nornheim and Ria. Though our work would have gone more quickly with you at the fore.
Odin: You must think I'm a piece of bread that needs to be buttered so heavily.
Thor: That was not my intent.

What's the meaning of all this? I am not a kind of philosopher guy, but is that a way for Thor to tell that Odin was old or weak or something to draw lots of black magic to survive wars? Why couldn't Odin go to wars?

Update:
Some are saying Thor was simply reporting without special meaning & he had a respect for Odin. Then, why did he not follow the order of Odin later in the movie? He did even insulted him at that time. So, Thor's words must have special meaning. Odin was clever enough to detect that, too. Or, why would Odin bother to say buttering thing in a serious conversation.

I want to know special meaning of Thor's words.
