In journalism, some rules are pretty clear.

White House correspondents don't wave campaign signs for the president.

Sports journalists don't ask athletes for autographs.

And reporters aboard the papal plane don't gush over the pope, receive blessings from him and offer him gifts.

Oh, wait ...

Rosa Flores is a CNN correspondent covering Pope Francis' visit to Cuba and the United States. And she's downright giddy about meeting the pope — and receiving a blessing from him.

Think I'm exaggerating? Check out this on-air exchange between Flores and CNN anchor Poppy Harlow: 

From a transcript of that conversation:

POPPY HARLOW, CNN ANCHOR: Our Rosa Flores is live in Havana. She has the extraordinary job of flying with the pope from Rome to Havana. She will be with him on this entire trip. 

Rosa, I have to begin as you tell me about this remarkable experience with showing everyone the photograph of the pope blessing you. What was it like?

ROSA FLORES, CNN CORRESPONDENT: You know, it was just such an incredible moment, Poppy. I really have no words to describe it other than he has just so much grace with people. We spent about 45 seconds together. We joked a little bit about actually a friend of his, a priest that I talked to before I got on the plane. And the priest told me, you know, "Give him a hug for me, Rosa. I didn't dare to hug a Holy Father. Let me just put it that way." But then the Holy Father goes on to tell me, Poppy, hear this. He says -- "This father, how dare he come to me two days before the conclave and ask me how I'm doing." He's like, who in their right mind would ask me that. Oh, with just such emotion, Poppy. Everybody around us. I can't wait to show you this video, because everybody just starts laughing. And then I had a tiny token, a small gift for the Holy Father. As you probably know, Mexican Catholics are very devout to Our Lady of Guadalupe, so I brought a little prayer for him, because, of course, I'm Mexican, Mexican-American. So you should see his face. As soon as he sees it, he grabs my prayer card from my hand, he starts kissing it. Oh, I almost went speechless, because I wanted to chat with him and I'm looking at the pope and he is just lighting up, looking at Our Lady of Guadalupe. Then, of course, I asked him for his blessing, and that's the picture that you were able to see.
