Families, converts/non-Muslims, and hijab/niqab.

So...For those of you ladies who wear hijab/niqab (either as a convert or non-Muslim)... Do your families know? If so, how did you tell them, and how did they initially react? If not, are you planning on telling/showing them?

I don't really know how to break the hijab to my family. Let's not even get started on niqab. I don't think they'd understand. Granted, it would be some time before I'll have to deal with seeing them, but... yeah. The thought of wearing hijab around my family is kinda scary and hard.
