Do you instinctively hide some of you from your friends and family?Which part of you to you hide and why?

I wouldn't say "hide" necessarily, but there are things I choose not to disclose. The fact that I'm a nudist, and some of my personal interests and beliefs as well. I'm not ashamed of these, It's just that most of these people would not understand nor accept them. I just choose to keep certain things to myself and on a need to know basis in order to curtail controversy and conflict.
