Well, that's what George's mom said to public radio's Marketplace.
Editor & Publisher tells the tale:
In a segment at the top of the show on the surge of evacuees to the Texas city, Barbara Bush said: "Almost everyone I’ve talked to says we're going to move to Houston."Is there a member of this family that can keep from giggling while talking about the utter destruction of a U.S. city and the horror that visted its citizens?
Then she added: "What I’m hearing is they all want to stay in Texas. Everyone is so overwhelmed by the hospitality.
"And so many of the people in the arena here, you know, were underprivileged anyway, so this -- this [she chuckles slightly] is working very well for them."
