...others just seem they CANNOT? why some are easily able to "hang out" with friends or friends of friends (just like on a reality show)..whether in a bar or pub or club or party or work etc?

and other just seem they feel very nervous and just cant..and are very aloof and quiet. etc?

how this depends and why, since how long has this been this way? has this always been the case or is it more modern thing? if so, why? what changes have been made?

please explain what you can...how do the "loner types" feel when in a group of people or in a room or working with someone ? and why?


thanks fo ryour answers!
WHAT DO PEOPLE WHO FIT INTO GROUPS OFTEN TALK ABOUT AND WHY THIS IS? WHY INTERESTING AND IS IT NOT INTERESTING TO QUIET ONES? WHY AGAIN?
