Ron followed both of them on to the lift, "Well, I say it's bloody hot outside, so something like sandwiches or salads?"
He knew that would please Hermione, and he went on, "There's that little place, in Mayfair near Hyde Park that would be nice? We can apparate there, to that spot in the park, and walk across the street. I've got some Muggle money on me."
He looked at Hermione and waggled his eyebrows, trying to get her to laugh some. He moved over to Harry's side and nudged him, "You both look different, you know. It must be the married life, and all of the 'benefits' you get. Poor me, always the bridesmaid and never the bride," and he let out an exaggerated exhale, "But some day, will be my day, I'm sure of it."
He moved in front of both of them, "So, I promise, no more marriage talk until I, too, have done the deed. Then we can all swap tales, and meet on Saturdays at the park and barbecue together. Isn't that what Muggles do on the weekends, Hermione?"
He liked poking fun at the situation; it was his way of making a potentially serious lunch turn to lighter topics. Better to get it out in the open, and be done with it
