For 30 years Jean-Claude Juncker has kept a black notebook with the names of all those who have betrayed him, the European Commission president told Belgian newspaper Le Soir.

“It is far from full because people rarely betray me,” Juncker said in a wide-ranging interview published Saturday. “So I don’t hold a grudge, but I’ve got a good memory.”

The 61-year-old said he began keeping the book — called “Le Petit Maurice” in reference to a German expression — because it amused him. One sometimes forgets these things, he said, adding that he never tells those who’ve crossed him more than he has to and what is already public knowledge.

“I take my precautions,” he said.

And he won’t be resigning under the weight of current criticism, he said, expressing his surprise that journalists “don’t analyze reasons which make certain people demand my resignation and criticize the Commission.”

The Commission president said he initially wanted to be a journalist himself, “and even an editor, as I love to play with words and ideas.”

He estimated he currently spends three hours each day reading “Belgian, French, English, Dutch, German, but also Bulgarian and Slovenian” newspapers in order to gather a “more accurate and complete image” of events.

Other topics in the interview included: remaining childless (“Being in politics at the rhythm that I was, I wouldn’t have been able to manage”); religion (“I believe in god. And it ends there. I don’t hear him, but he must be somewhere”); Nigel Farage (“I respect the man, he’s very funny and very erudite”); rumors of alcoholism (asked if they were false he said “Yes!”); and his predecessor’s decision to take up a job with Goldman Sachs (“the fact that [José Manuel] Barroso is working for a bank doesn’t bother me very much. But for that bank, that’s a problem for me.”)

He also defended the choice of Frenchman Michel Barnier to lead the Brexit talks on behalf of the EU, saying: “The British don’t like him but that doesn’t mean that he doesn’t like the British.”

His sadness at the U.K.’s departure stemmed, he said, from the need to now spend “two or three years on deconstruction instead of consolidation. Finding the right balance between the two is difficult.”

And he did not rule out Donald Trump becoming U.S. president, saying “everything is possible in societies that no longer reflect and [Trump’s] simplistic proposals are heard everywhere, including in Europe. We can’t teach others lessons.”
