Pity Us

I have to help my sister buy diet pills today. Her stock will be finish soon, so she requests me to buy for her when I am visiting to the shop. Pity us, why have to depend on diet pill to loss weight often? I have no idea why I could not maintain my weight without those pills. No matter how I tried I would easily gain weight also. I even told my friend I would easily gain weight even just drinking water! Pity…
