Linus: Never jump into a pile of leaves with a wet sucker.
Sally Brown: If you try to hold my hand, I'll slug you.
Sally Brown: Is Linus taking me to the party?
Lucy Van Pelt: That stupid blockhead of a brother of mine is out in the pumpkin patch making his yearly fool of himself.
Violet: Boy, is he strange.
Sally Brown: But maybe there is a Great Pumpkin.
Lucy Van Pelt: What kind of costume is that?
Charlie Brown: He's a World War I flying ace.
Lucy Van Pelt: Now I've seen everything. All right everybody, we'll go trick-or-treating, and then over to Violet's for the big Halloween party.
Lucy Van Pelt: All right, all right! Let's bob for apples! This is the way to do it.
Schroeder: Yeah, Lucy, you should be good at this. You have the perfect mouth for it.
Linus: Each year, the Great Pumpkin rises out of the pumpkin patch that he thinks is the most sincere. He's gotta pick this one. He's got to. I don't see how a pumpkin patch can be more sincere than this one. You can look around and there's not a sign of hypocrisy. Nothing but sincerity as far as the eye can see.
Answer: From what I've seen, usually Sally is often annoying Linus with her flirting when he has nothing in common with her, or he's just trying to do something to help her and she tries to make it into more. Here, Sally's comments make Linus think she believes in the Great Pumpkin too, or is at least interested in hearing more about it. It's more that he's excited she likes the same thing as he does. Later in the pumpkin patch, he's happy she's there because he wants to share the experience with someone, not because he has any feeling towards Sally.
