Am i doing too much?

A fundamental principal in social skills is “Talk about the other person interest”. I have different friend circles where i keep different personality precisely for knowledge and somehow examine human behaviour.

I realised in one of the friend circle, i used this principle too much and the result is that friends know about each other very much then they know me. It’s not like they started pushing me out of the group or do not like me. But they just don’t know me enough. I have done too much to talk about their interest and i think i become an expert in this.

The friends nowadays sometimes approach me like talking of my shits but i manage somehow.

Any other person with similar experience or advices?
