He already had the information about my pay; so it was too late to stop him. Besides, any employee with computer access at the IRS or the Social Security Administration can look your salary up.

My main goal at the time was maintaining a low profile, and a good social engineer doesn't advertise his abilities and knowledge. You always want people to underestimate you, not see you as a threat.
