While more than 1,000 mourners gathered Saturday to remember former first lady Barbara Bush, her husband paid tribute to his late wife in a special way: with his socks.

George H. W. Bush, who is known for his love of colorful socks, wore a special pair of book-themed footwear in honor of his wife's longtime commitment to literacy.

Jim McGrath, the official spokesperson for the former president, shared a photo of Bush's socks on Twitter. He noted that Barbara Bush raised more than $110 million for the cause she championed for three decades.

Elsewhere, George W. Bush was giving us all the feels, with a sweet anecdote recounting his last visit with his mother the week before her death.

Speaking in an interview with PBS Newshour, the younger Bush described how his mother was "slightly feisty still" even while she was in the hospital. 

"She and I used to kind of needle each other in a friendly way," Bush recalled."She was teasing me and then the doctor walked into this hospital room. And mother said, 'You want to know why George W. is the way he is, doctor?'

"Because I drank and smoked while I was pregnant with him."
