Shalysse is scheduled to open the medical office this morning. The clinic opens at 8 AM, so she arrives at 7:25 to open the office. As she is walking from her car to the building, she hears footsteps behind her and turns around, but no one is there. She continues to walk toward the building, but hears the noise again. Again, no one is there when she turns around. What should Shalysse do? 

A. Turn around and yell for whoever is stalking her to stop it
B. Notify the facility's security
C. Continue walking toward the building as if she had not heard anything
D. Run to the building as quickly as possible
E. Hide in the nearest bushes or doorway

B. Notify the facility's security
Shalysse has heard the footsteps twice, but was unable to locate their source. She should use her cell phone to notify building security immediately, and wait for another staff member to arrive before approaching the building.
