It is more fun to talk with someone who doesn't use long, difficult words but rather short, easy words like "What about lunch?"

The line gently satirizes pretension in conversation: people who rely on “long, difficult words” can be less enjoyable than those who speak plainly and sociably. By contrasting lofty diction with the homely, immediately human question “What about lunch?”, the quote suggests that warmth, shared everyday needs, and ease of understanding matter more than verbal display. It also reflects a childlike preference for concreteness and companionship over abstraction—an attitude often associated with Milne’s comic sensibility and his interest in how ordinary speech builds rapport.
