Pope Francis wants youngsters to BRB from their cellphones at the dinner table, warning that the lack of face-to-face communication with adults could result in “war.”

“When we’re at the table, when we are speaking to others on our telephones, it’s the start of war because there is no dialogue,” the 80-year-old pontiff told students last week at Roma Tre in Rome.

The pope also chided today’s youths for their lack of manners, saying that instead of a friendly “good morning,” they opt for an “anonymous ‘ciao, ciao.’”
