It's always slightly strange to go immediately from one group of people in your life to a completely different group of people in your life. The contrast is sometimes so stark, it becomes almost confusing.
It's like this. I know who I am. I know which parts of me come out when around certain people. I am very comfortable with that. Then, when I'm around other people, I become a slightly different person. Does this make sense to any of you? It's like I'm a person from the past, and then I start to get muddled about who I really am now. It feels almost like straddling two worlds. I have one foot in one world and one foot in another and I just have no idea where I really belong anymore. I don't only mean personality-wise, I mean hashkafically, too.
Unless I just create my own world called Erachetland. Uh...come visit, sometime. It's lonely all by myself in there.
