What would you do if you're being watched?

Not many people like to be watched. I personally do not. However, there are so many situations when you need to find information about people that are very valuable to you. May be there is a lie or your sweetie doesn’t want to be with you and don’t know how to break up? I would like to know more about. Please post your thoughts, which will be very helpful for me to find if we really have a need in Private Detectives. Thank you.
