Pope Francis shows irritation for first time during Mexico visit

For the first time on his trip to Mexico, Pope Francis has publicly showed signs of irritation. 

Following a colorful encounter with young dancers and singers in the western city of Morelia, the Pope went over to greet the faithful on Tuesday. 

Some overly eager people tugged on his sleeve from behind a barrier and appeared to be on the verge of toppling him. 

After it happened a second time, Pope Francis got a cross look on his face and said, "Don’t be selfish, don’t be selfish." 

The Pope took a couple of steps back as appeal came over the public address system asking the crowd not to clump together. 

He continued to wave to people for a few minutes before leaving.
