My sister had her friend over lastnight, and I noticed that over the past year, she's gained a lot of weight. She used to have a flat stomach, but now she has belly almost as big as my sisters. I think that she influenced her to get fatter. My parents were gone all day, and I was home alone with my sister and her friend, basically all they did was eat and watched tv. Its weird how she got her friend to gain weight too, oh well. Thanks anyway Candy, but nothing is helping.
