Yes, that was the impression I got when Raul mentioned that, prior to doing "The Homecoming", he spent a weekend at Jim Dale's home in the country, working on his accent for the play. Now, I could be wrong, but it seems to me inviting someone to your home for the weekend, even if you plan to work, is something you do for a friend, and not a stranger (and they've known each other since they worked together in "Comedians", too).
Sarcasm is an allergic reaction to stupid people.
