I have a lot to hide.

I want to hide what sandwich I had for lunch. I want to hide what book I'm reading at the moment. I want to hide what my favourite mug is.

I want to hide lots of things about my life that are legal and socially completely acceptable.

Why do I want to hide these legal and socially acceptable activities? That's also something I choose not to divulge.

Should I be allowed to hide these things?
