Have you ever felt violated? It is an awful feeling. When someone lurks around but doesn't make their presence known. When you don't share a private part of your life but they invade it anyway but don't come out and tell you, rather they sneak around and then make an off the cuff remark that makes you realize they have been lurking in areas of your life that you hadn't shared with them.
If it was an accident that they stumbled upon this area of your life that you hadn't shared with them, then why wouldn't they comment about it? Why make an off the cuff remark so that you would know they have invaded your space but they don't come out and just say it? Oh, it makes me so angry.
