'This Is Your House, Too'
[After the death of his 16 year old son in 1924], Coolidge took solace in service. The nature of the service he needed to render had changed over the years. Service as vice president had meant diplomacy, then the service of continuity; now the service was the tax legislation. But even more than before, the idea kept him going. Selden Spencer, a Missouri senator who had visited that summer, told a story about him. One day, walking with the president on the White House grounds, Spencer had pointed to the White House and made a joke: “I wonder who lives there?” “Nobody,” Coolidge had replied. “They just come and go.”

At a "workshop" for the film 42 in the State Dining Room of the White House, First Lady Michelle Obama told the assembled guests that "this is your house, too."
"I want to make sure that you all know how welcome you are here in this house, because the truth is we do these things -- we make sure that we do these workshops so that you all know that this is your house, too," Obama told the guests. "So we want you to make yourselves at home. We want you to feel good and relaxed and learn and ask questions, okay?"
The White House is currently not allowing the public to tour or access the White House. Only invited guests are allowed inside.
