After the White House tour, Mrs. Bush joined her husband across the street outside the Blair House where they met with Melania andDonald Trump.

The meeting of past and present presidential couples came hours after Trump announced onTwitterthat they would gather at the official guest residence.

Trump’s spokeswoman Stephanie Grisham did not immediately respond to PEOPLE’s request for comment on the White House and Blair House meetings.

The ritual and protocol of a state funeral also forced a graciously Bush-style cordiality between his family and President Trump, who has crudely insulted them for years.

“The mean Twitters and the name-calling—Bush found that gauche and that is why Barbara Bush did not want Trump at her funeral,” presidential historian Douglas Brinkley, a Houston friend of the family tells PEOPLE.

But for his own services, Bush recently told his former vice president, Dan Quayle, that Trump would be welcomed. “He mentioned having Trump at his funeral because it is protocol and George had deep respect for the office of the presidency—so he would have it no other way,” Quayle tells PEOPLE. Adds former Republican Sen. Chuck Hagel, also a friend, Bush “placed a high value on courtesy. He was typical of the World War II generation— humble, gracious and decent.”

Mrs. Bush and Mrs. Trump’s friendship was first formed after the January 2017 inauguration. “I’ve talked to Melania. I’ve been back and had tea with her,” the mother of two toldCNNin November 2017, adding that Melania has “done a lovely job” as first lady and that she is a “wonderful representative for the United States.”

The Bushes have been in Washington D.C. for memorial services honoring the former commander-in-chief, whose body is lying in state at the Capitol Rotunda ahead of private services Wednesday at National Cathedral.
