A cartoonist tugged at the hearts of Americans with a sketch set in Heaven and four simple words: "We waited for you." The scene shows the former president reuniting with Barbara Bush, his late wife of 73 years, and Robin, their daughter who died of leukemia at age 3.

2.) Sully the service dog

A yellow Labrador named Sully joined the Bush family to comfort the former president after the passing of Barbara Bush in April. The two formed a close bond, which became evident in a moving photo posted by former White House spokesman Jim McGrath

Sully's next mission will be working alongside other service dogs at Walter Reed, according to America's VetDogs.

4.) Sneaking candy to Michelle Obama

The nation's 43rd President George W. Bush greeted President Trump, his wife Melania, and former presidents and their spouses seated inside the National Cathedral.

As Bush greeted former First Lady Michelle Obama, he reached into his pocket to share a piece of candy with her, a sweet tradition between the two. She refers to Bush as her 'partner in crime' after years of sitting together at official events.

5.) Touching eulogy from former President George W. Bush

First-born son and former President George W. Bush delivered an emotional tribute to his father at Wednesday's State Funeral.
