What is the most popular reason for your 'secret admirer' not wanting you to notice them?

[Anonymous]

They like to watch, but don't think you'd ever actually go out with them.

They aren't ready to approach yet, but when they are they will make themselves more obvious.

Their feelings might be too strong and they're afraid you will get scared of the intensity.

They have nefarious intentions.

It usually always comes down to a fear of being rejected and ridiculed. Read into the psychological effects of rejection, it is interesting and you can learn a lot about people's social behaviors. Rejection from a loved individual many times can be psychologically perceived such as physical harm or pain. In some way this is a light form of heartbreak. So yeah it's very common that people are afraid to let others know of their feelings.

Not usually means not interested although it can mean shy. It is likely you do not recognize her cues if they are not Textbook
