I should care, but...

I just don't... My sister, who is like nine by the way, said she caught me watching jgv. And she also told me that she apparently told my mother. The sad thing is that I can't bring myself to care. She said that "mom needs to know what her little girl/princess is doing." And I'm just like "No. She doesn't. I'm 21." I really don't know why I'm not bothered by this or if I should really even care that she saw it. I kind of want to laugh but then I'm like this probably isn't funny. She told me she saw it before and I'm like "okay. So?" Part of my wonders if she just wanted something to hold over my head. Lol Because all of a sudden she was like I could cut your hair while you're sleeping or something like that. She doesn't exactly know what it is but she just kept calling it gross or whatever. Lol She was bugging me for a good part of the day about it and when she told me she knew I'm just like "Am I supposed to care? Like, is it supposed to matter to me that you know?" I don't even know what to say or feel about it. But I really do just want to laugh. I don't know why I'm so amused. orz
