My bag

I always have a lot of things to carry with me. I thought my bag was heavy because it was big. I was wrong.
2 weeks ago I bought a bag. I instantly liked it when I saw it at the shop, but it was smaller than the one I usually use. I couldn't decide whether to buy it or not. Though I needed a new bag because my bag had broke. Then the shop staff told me "Please put fewer things in your bag". Surely, I agreed with her because there were unnecessary things in my bag. I decided to buy the bag.
I immediately use the bag the next day. After one week, unfortunately I couldn't eliminate my things. The shape of my bag transformed into a strange shape. It was easier to carry by my shoulder than to carry it by my hand. But I couldn't even hang it from my shoulder because the handle had become shorter due to the many things in side the bag. I gave up using the bag. I bought another one which was the usual size.
