What really grinds my gears…

Ok, so there’s this girl I go to school with. Nice girl. Friendly. Caring. Whatevs. Well when I first met her she liked to poke me….. literally. So I asked her to stop… On about 5 different occasions. I told her I’m not a very touchy person and it really aggravates me when she does it. FINALLY, she stopped. Well after being separated from that class for a while, I began to let things fester on my mind about this girl. Now, I’m a bigger girl. BUT, I make myself look nice. I do my hair, my makeup, get my eyebrows done, blah, blah, blah, but I make myself look nice. And I like to think my personality is pretty awesome so I think that makes me a prettier person in the long run anyways. But I also at least attempt to watch what I eat. And when I do eat it’s in decent proportions. Well this girl (Jackie is her name b-t-dubs), doesn’t take care of herself. She doesn’t shower as often as she needs to, her hair is always gross looking (and we’re in HAIR SCHOOL for crying out loud!!), she doesn’t dress to fit her body type, and the girl is ALWAYS eating. No joke. We get to school at 10ish, and she has breakfast before she leaves, and when she gets to school, she always has some sort of peanut/candy mix or chips or something. She eats them until lunch at noon. For her lunches, she brings enough food for 2 people. After she’s done eating, she goes to her car and stocks up on her peanut/candy mix or chips or whatever floats her boat that day, and eats some until lunch is over at 1, and then continues to eat them until break at 2:30, refills on break, then eats some more until school is over at 5:30. And when we’re in class, she’ll sit there and basically BRAG about what she had for breakfast and how she was STILL hungry afterwards. There was one day she ate an entire box of french toast sticks with syrup, and still had room for more. My question is, how on EARTH can someone do that?? How can you come up with all these excuses on why you eat so much?? First her reason was because she was “pregnant.” Found out that wasn’t true because she has still YET to have a doctor appointment, and she’s been claiming this for 3 weeks now. Second reason was because she doesn’t eat at home ever. LIE. She cooks dinner every night AND tells us how much she had plus how much she had at breakfast the next morning. It’s kind of ridiculous. Another question I have, is how can you for real feel that the way you portray yourself is acceptable?? If I were ever to portray myself like that I would be slapped. I think if her mother saw her she’s be slapped as well. But who knows?? She wears sweatpants and shirts that are FAR from flattering. It’s like she tries to show to the world all her rolls and cellulite. I know this is making me sound like a total bitch, but I guess the reason I’m writing this is because I want someone to help me understand how someone could do that to┬átheir self. I don’t know. I know she has money so I know she can afford to take care of herself. You can tell she doesn’t brush her teeth, she needs her brows done to an extreme, and needs to buy clothes that fit. If she actually showered and washed her hair, and then actually styled it, she might just look presentable. You know you don’t wash your hair enough when we bring you to the shampoo bowl, wash your hair twice, and it still stinks. Then she gets mad at me, Miranda, and Jenna because we talk to all sorts of people and have a lot of friends, when us 3 are her only friends. Can any one help me to understand this??
