Bill Clinton gifts George H. W. Bush socks during Houston visit

Former presidents Bill Clinton and George H. W. Bush saw each other on Sunday, and spent at least a portion of their visit talking about a relatively mundane clothing item -- socks.

Clinton tweeted out a fun image of the pair on Sunday, revealing in the caption topics of conversation between the 41st and 43rd American presidents.

"Great to spend time with @GeorgeHWBush & Mrs. Bush in Houston today," Clinton's tweet read. "We caught up about kids, grandkids, old times and new times. And socks."

A pair of socks can be seen in the image, indicating that Clinton has gifted his presidential friend another pair of socks -- an item Bush historically appreciates and has collected in recent years.

Bush 41 has developed a fancy for fun socks throughout the years, and expressed in a 2013 note a point of contention between he and his wife over his sock obsession.

"I absolutely love a crazy pair of socks," Bush's note read. "Barbara, on the other hand, has had enough."

Whether the former first lady will allow another pair of socks to enter her home remains to be seen.
