I tend to not reveal my deepest emotions. I was slightly more expressive when I was younger, but when I would reveal my ideas or emotions as a kid, often I would get laughed at. I found that many of the people I was around were dealing with life at a more surface level and if and when I shared my more inner thoughts they would just distance themselves. That made me feel more strange so now I would only reveal my true thoughts and ideas to those I become close to and trust.
For the rest of the world, I just give the more practical information and try not to express too much of my own opinions.
