Double eyed mask

Someone who is always anonymous and quiet and never talks about anything about themselves at all. They often wear masks or bags with two eye holes in them, which is where this term originats namesake from.

She’s definitely a double eyed mask cause she doesn’t talk about anything about her life. She’s been quiet for quite a while and I want to ask her what’s happening with her but she won’t say anything. I am scared and worried for her and I want to help her somehow.
