Is "вы" always capitalized in writing when you are addressing only a single person?  Or is this optional and you can leave it uncapitalized? Also, what about other forms of the word, such as

вас / вами /вам...

I assume they are also capitalized just as "вы" is?

What about the "вы"-based adjectives : ваш / ваши / ваша / ваше?

Thanks!
