I'm a chameleon, really. All I do is latent inside of me to begin with. I stretch and shift according to the group I'm with or just the individual. It's natural for me. I'm different with everyone. I'm not a user of an object, I'm an organism, so that makes it less likely for an identity crisis to occur, but I also accept that what I portray is who I am, in part. I never portray something I don't like, such as a bully or something like that. Nothing distasteful or that garners ill regard from myself.
Just be honest with yourself. When you say something you don't actually feel, stop and reflect on it. Analyze it. If you're not sure, think about it, if you can't come up with an answer, come back to it on another day.
