Charlie Brown: Stop the music! All right now, we're going to do this play, and we're going to do it right. Lucy, get those costumes and scripts and pass them out. Now the script girl will be handing out your parts.
Lucy Van Pelt: I know how you feel about all this Christmas business, getting depressed and all that. It happens to me every year. I never get what I really want. I always get a lot of stupid toys or a bicycle or clothes or something like that.
Charlie Brown: What is it you want?
Lucy Van Pelt: Real estate.
Lucy Van Pelt: Pig-Pen, you're the innkeeper.
Pig-Pen: In spite of my outward appearance, I shall try to run a neat inn.
Lucy Van Pelt: You think you're so smart with that blanket. What are you going to do with it when you grow up?
Linus Van Pelt: Maybe I'll make it into a sport coat.
Charlie Brown: Pig-Pen, you're the only person I know who can raise a cloud of dust in a snowstorm.
Lucy Van Pelt: Look, Charlie, let's face it. We all know that Christmas is a big commercial racket. It's run by a big eastern syndicate, you know.
Charlie Brown: Thanks for the Christmas card you sent me, Violet.
Violet: I didn't send you a Christmas card, Charlie Brown.
Charlie Brown: Don't you know sarcasm when you hear it?
Patty: Try to catch snowflakes on your tongue. It's fun.
Linus Van Pelt: Mmm. Needs sugar.
Lucy Van Pelt: It's too early. I never eat December snowflakes. I always wait until January.
Linus Van Pelt: They sure look ripe to me.
Lucy Van Pelt: Get the biggest aluminum tree you can find, Charlie Brown, maybe painted pink.
Shermy: Every Christmas it's the same. I always end up playing a shepherd.
Answer: He never asked about the "true" meaning of Christmas, only that he was depressed about it. He didn't have the Xmas spirit. The feelings of love and compassion. He was talking about Santa Claus and gift-giving, but Linus told him what Christmas is all about.
