House Speaker John Boehner cried Friday as he announced his resignation to a gaggle of reporters. That's right. The Ohio Republican cried in public. Again.

Boehner's resignation Friday shocked the political world, including President Barack Obama. Boehner said he woke up Friday morning, said his daily prayers "and I decided, you know, today's the day I'm gonna do this. Simple as that."

Boehner said he was tired of waging political battles after months of mounting pressure from the far-right caucus of his party. Obama said Boehner would be remembered as a good political leader who worked across the aisle.

But for many Americans, Boehner will also be remembered as a man in touch with his feelings. During his more than 20 years in officer, Boehner has often been photographed crying while performing his duties.

He cried at least twice this week alone. Before his teary press conference Friday, Boehner became emotional listening to Pope Francis address Congress Thursday.

He cried in February 2007 after U.S. Rep. Sam Johnson (R-TX) shared details about his time as a prisoner during in the Vietnam war. Johnson said opposition to the conflict hurt the morale of troops on the ground and urged lawmakers to support the U.S.-led conflict in Iraq at the time.

He got emotional after Obama unveiled a statue in honor of civil rights activist Rosa Parks in Washington in 2013.

He's also been moved by activists from other nations. Boehner cried in September 2012 during a Congressional Gold Medal ceremony at the U.S. Capitol.

But it's not just civil rights leaders. Former presidents can also drive Boehner to tears.

And, naturally, he isn't above crying for himself.

Boehner also isn't too shy to make an ugly cry face in public.

It's unclear why Boehner is so inclined to cry in public. He is the second oldest of 12 brothers and sisters and grew up in southwest Ohio, which isn't exactly known for breeding sensitive men. He worked as a night janitor at one point before opening a small business. He has served in Congress since 1991, which perhaps would make anyone prone to bouts of crying.
