Someone falls into the water from a dock. what is the first thing you should do to this person?

If someone falls into the water from a dock, the fist thing you should do to help this person is: Throw a life preserver toward that person
In every dock, a life preserver will be placed near the water for this type of situation. After you throw it, you row it, reach the victim, and check if the victim could breathe properly

The lutherans i believe. i hope this : )

This would be a example of a "i want to be single person"
