A woman on the sidewalk blocks the sun from her eyes to peer down the street.
A woman is attempting to recognize a friend she thinks is approaching.
The woman is not necessarily attempting to recognize an approaching friend when she peers down the street.
She may not be trying to recognize the friend but trying to get a better view
Just because a woman on the sidewalk blocks the sun from her eyes to peer down the street does not mean she is attempting to recognize a friend.
