I was at this huge festival in Barcelona, eating my sandwich very calmly, when this tall, strong guy in a very tight white T-shirt, came up and stopped right next to me. He gave me a smile and a friendly nod and even though it was a few gestures, he was so polite that I almost offered my sandwich. In less than five minutes, the surrounding people started staring at him and gossiping, and then he looked at me, straightened his white T-shirt like someone who was going to run, grinned sheepishly and walked into a door at the side of the stage. Hours later, I noticed that this tall, strong guy was on stage and was the guitarist of a super famous rock band.
