Yes

This is not the first time this opportunity has been presented to you, nor will it probably be the last. You have done this before, it's become almost an art form. You make sure that she is still unaware of you, turning the corner widely to avoid her peripheral vision. You flip your phone to the camera, and wait for her to take another step. When her right leg ascends a step above her left, you dive in, hitting the shutter button you snag a shot of her luscious legs and ass underneath the skirt, a classic shot that is taken with expertise. You feel proud of yourself, appreciating the photo while making sure the girl knows nothing of what just happened. The young lady exits your sights as she is lost in the hallway and you save your snapshot.
