Do you become like the people you are around? Is this common for INFJs, especially as children? I've noticed within myself, that I pick up someone's speech and mannerisms if I am around them for some time. It seems so easy for me to lose myself in others sometimes. Not so much anymore I think, but especially as a child, I internalized a lot of my environment when I was younger - ex. adopting family members' beliefs in place of my own.
