<human>: Can you give me the gist of the text in a nutshell?

My sister is turning 17 this month and is still completely uninterested in forming any personal grooming habits. She showers nightly, but that's about it. She still has to be reminded to brush her teeth, and she NEVER applies deodorant on her own. She also likes to reuse shirts 4 or 5 times before washing, and all her shirts stink because she won't use deodorant. Every single time the family leaves the house together, someone has to tell her that she stinks and needs to put on deodorant and change her shirt. And even though she'll do what she's told, she'll always say that she can't smell herself and didn't know. And my sister does have a working sense of smell, she's just so used to her own stench that she doesn't notice it.

Now, my sister does have Asperger's and she is a very smart girl who takes her academics very seriously. I once had a serious conversation with her about her grooming habits, and she says she doesn't take the family very seriously when we say she smells because we're *always* telling her that. She said that if someone at school said something to her about her stench, she'd take it more seriously. I told her that her classmates were being polite by not addressing the way she smells, but she just didn't understand. 

I'm worried that my sister will graduate next year without ever caring about her personal hygiene. I don't want her to be known as the girl who always smells.
<bot>: My sister smells awful and is ostracized by her peers. How do I get her to realize that personal grooming is important?
