I am not the social kind of person. Was always more like a social Chameleaon (see NMMNG).

My girl is all into this Christmas presents kind of stuff. Giving me all kinds of presents which are really well thought. I don't do this.

I can see, that she is expecting the same. She didn't make a fuzz about it but I can see it.

I have always let the social stuff be handled by my SO's which depend the problem.

From your opinion is it worth investing in social skills when you don't really care? Should I care? And what are the recommended readings and trainings on this subject?
