Stay with it and let people know what to expect from you.
If you keep them guessing because you have other agendas they are ill at ease, unable to understand your intentions.
They will become reserved and cautious with you.
But when you are consistent with your habits, demure, moods and the way that you treat people they feel more relaxed in your presence.
This makes you more acceptable in their eyes.
They know what to expect from you and they feel safe in your company.
