The boy was seven or eight, and the girl was five or six.
Seven to eight meters behind them, a man and a woman were pulling suitcases behind them as they discussed something, and didn't notice Luke's actions.
Luke only took a handful of seconds. When the couple saw their children run off and pull at the security guard at the entrance of the ballroom to ask something, they hurried over, and realized that the children wanted to pee.
The woman found that odd. "Didn't you just pee before we came out? You're just playing around again!"
The man apologized politely to the security guard.
What could the security guard say? There was nothing wrong with a kid who really needed to use the bathroom.
He told them where the bathroom was, waved goodbye to the family, and returned to the ballroom entrance.
Luke, on the other hand, had already entered the dimly lit ballroom. Moving nimbly, he stood in a corner.
