Is it normal that some people ask others if something is normal?

I mean, normality is subjective and cultural... don't you think? I know about a lot of people that don't know what's normal and what's not, but they don't realize the answer to this question is inside their own consciousness and that this answer can be positive depending on the environment, religious, social life and relationships.

* I know, I used 'is it normal' because this was a good statement to start the question...
