I went to the restroom only to find a heated debate over who used the soap first when wading their hands. It went as follows:

Younger sibling: I win!
Older sibling: I won.
Younger sibling: I win!
Older sibling: I won.
Younger sibling: I win!
Older sibling: I won.
Younger sibling: I win!
Older sibling: I won.

This continued for the majority of the time I was in the restroom.
