Returning to the nudist lifestyle?

I haven't gone nude around the family house in years, since I was 13. My parents are lifelong nudists. I will be spending a month of vacation at the family house this holiday season. And, while I'm very comfy disrobing in my own space currently (to the point my roommate thinks it's weird when I wear clothes), I'm nervous returning to my family's nudist ways after they've not seen me do so for so long. Should I tell them I'll be going nude ahead of time or do so and act like it's nothing?
