Let's see what happens if I follow her.

You walk over to the door an look out to see if you can see where she went. You see her heading up the street and so you slip out the door and begin to follow her. Shes up a block ahead of you and she turns the corner. You better hurry up or you will lose her.

You step it up and get to the corner and look down the street. There she is, but she is stopped looking in store front window.
