You and your little brother were at a theme park.

You were standing in line for a rollercoaster but when it was your turn there was only one place left. Your brother said that he could go alone and you said okay.

You saw him struggle putting on his seatbelt, but then the guy sitting next to him helped him. Soon the rollercoaster started.

After around 2 minutes they came back. Your brother ran back to you jumping with excitement and after him came the guy that helped him with his seatbelt.
