Acting?

Have you ever caught yourself acting differently with one group of people/friends than you do another? I do occassionally. Partly because, one group I've known forever, since high school and they knew me as I was back then. A quiet, extremely shy person. Over the years, I have become a little less shy and more outgoing. But for whatever reason, when I'm with my friends from high school, I find myself reverting somewhat back to that shy person. Not nearly as bad, but not anything like I am at work either. I wonder why I can't just be the same way with both groups. I am working at being more the same with all groups of friends that I know. I wonder

Realizing this made me start thinking about the 'faces' I wear at times. I am a sister, an aunt, a great-aunt, a friend, a co-worker, an employee, a person who collect pop bottle tops because I forget to throw them away (seriously, I find them everywhere!). When dating someone, a girlfriend, to name a few. How do all these titles affect ones behavior and they way they are seen by others? I wonder....
