The condolences and Kleenex-worthy moments have been flowing since former president George H.W. Bush passed away Friday evening, with people sharing anything from touching memories to examples of the 41st president’s grace, class, and integrity.

Bush family spokesman Jim McGrath tweeted a photo today that showed dogs truly are man’s best friend.

Mission complete. #Remembering41 pic.twitter.com/rXdyXAS4lk

The photo shows former President George H.W. Bush’s dog Sully lying in front of Bush’s casket, with the caption “Mission complete.”

Bush adopted Sully in June from America’s VetDogs, which trains service dogs and provides them to veterans for free. Sully is named after Chesley “Sully” Sullenberger III, the airline pilot who safely landed a passenger plane in the Hudson River without losing a single one of the 155 passengers on board. The younger George Bush revealed on Instagram that Sully will now head to Walter Reed Military Medical Center to aid other veterans.

McGrath has previously shared photos of Bush and Sully, including Sully accompanying Bush into the voting booth.

Former First Lady Michelle Obama revealed that she will be postponing parts of her book tour in order to attend Bush’s funeral and urged readers and ticket holders to join her in “paying tribute to [Bush] and his tremendous contributions to our world.”

I hope readers and ticket holders will understand my decision regarding my desire to attend President Bush’s funeral, and join me in paying tribute to him and his tremendous contributions to our world.

The U.S. Navy also mourned Bush’s death on Twitter. Bush had enlisted in the Navy on his 18th birthday, just six months after the attack on Pearl Harbor, and was commissioned as an ensign less than a year later, making him the Navy’s youngest aviator.

President Bush flew 58 combat missions as a navy pilot during World War II and was awarded the Distinguished Flying Cross and three Air Medals. He was honorably discharged in September 1945 with the rank of lieutenant. #remembering41 pic.twitter.com/ipCfZtiOns

And others pointed out that Bush is now reunited with his beloved wife of 73 years, Barbara (who passed away in April of this year), as well as his daughter Robin (who passed away due to leukemia in 1953 at the age of three years old).

Barbara Bush used to sit on the steps of the South Portico at the White House, waiting for George Bush to return from trips. I thought of this picture tonight, and how happy she must be that he's coming home to her again. pic.twitter.com/3BEidkAyrL

Cartoonist Marshall Ramsey, who had drawn Barbara’s reunion with Robin in April, created a new one to show the two reuniting with Bush.

Godspeed, President Bush. pic.twitter.com/6xapcfnCxU

Jenna Bush Hager, Bush’s granddaughter, revealed on Instagram that the cartoon brought comfort to her because Bush had told her he was looking forward to being reunited with his loved ones. Over the years, Bush often expressed the belief that family was the most important thing in life.

After a long and varied career in business and politics, President Bush was asked what he felt was his greatest accomplishment in life. Without pause he answered, “That my children still come home.” #remembering41 pic.twitter.com/E60AwJseEN
