My sister is so cruel, she keeps telling me about times when she's been cruel to others in school, like it's some kind of good thing. And I mean extremely cruel, at the same time she's friendly to me, so I'm just nodding and smiling, while thinking to myself that my sister is one of the worst people I've ever met. So self-centered too, she only talks about her experiences, and 'weird' guys she dissed. Whenever I say something, she's not interested. I think my sister is a cruel narcissist. She also keeps talking about her obesity and how hard it is for her to lose weight due to some disorder, well, not to be mean to obese people or anything, I know genetics play a very big role. But maybe if my sister stopped drinking Coca Cola all the time maybe it would be easier for her to lose weight, and maybe if she actually, you know, exercised. I wouldn't say this to her though, I'm just too nice.
