How do I get across that river?

A dumb blonde is walking along, lost, and encounters a deep and wide river. She looks up and down the river for a way across but is unsuccessful in finding one. Yet, when looking to the other side again, she happened to see another blonde on the opposite river bank. She tried calling to her. “How can I get to the other side of the river?” she shouts loudly. The other blonde replied “What for? You are already on the other side of the river!”
