You are in the plaza with your friends. There are different lanterns and decorations; even though it's made of recycled materials, it's still pretty.   After a few minutes of taking a walk around the plaza and buying different street food, a glowing balloon caught your attention. You've always wanted one of those, but you thought to yourself that it was only a waste of money. You kept on glancing at the balloon until Nathan, one of your friends, noticed it.   "Guys, I'm going to the bathroom; please wait for me," Nathan said to y'all with a smile before walking away. After waiting for Nathan to return, he's finally back. But he has a glowing balloon in his hand. Nathan walked towards you and handed you the balloon.   "Okay guys, let's go," Nathan said with a smile on his face.
