How to get across the river

A blonde once got lost near a river. She traveled up and down it searching for a way to get to the other side. She tried walking in the shallow part of the river, and she even tried grabbing onto a branch that stretched half way across the river to try to swing to the other side. No matter how hard she tried she couldn’t get across. After many failed attempts, she finally felt like giving up. Yet, at the last moment, she saw a person walking by and decided to follow her–across the bridge.
