Friends Meshing

I have a hard time mixing a group of friends with another group of friends. I don't know why that is I mean you would think if I got along with this group that they shouldn't have a problem with this group. I'll admit, do at times act a little different with a group than another... Now that I'm thinking about it, I might be socially self-conscious that I'm too afraid to be judged by who and how I interact with other people. I know that I do have a group of friends that are very judgmental and it would break my heart if they do not like another group of friends, also they would be the people that wouldn't hold back on expressing how they would feel about a group of people.

I don't know... I'll slowly try to move people around.
