An intriguing event unfolded today at the airport. Initially, I checked my luggage and proceeded to find the facilities, which I located without difficulty. While exiting, a tall man wearing sunglasses inquired, "Could you direct me to the services?" At that moment, a girl appeared exclaiming, "It's Felipe Brunardo!" He is the lead singer of my favorite rock band. Twenty girls rushed towards us. Felipe headed to the facilities while I remained, and all the girls engaged with me and took pictures. What an amazing experience! Meanwhile, Diego found his time at the airport quite dull.
