In last month, I went shopping with my parents, and we bought many things. These were useful things and necessary for housework. We bought some cooking thing because after Covid-19 pandemic, we wanted to go outside and bought new things. Everything which we bought, were replaced the old things in our house. I think the most useless thing which costed much money was my sister's toy. When I was in her age, I didn't have a lot of toys like her. Therefore, I think it was very useless and expensive.

Last week, my whole family went shopping at a big supermarket in the city. We bought things that were useful and necessary for housework. My family bought a lot of fresh food. Our family started to buy new things such as phones, computers, tables, chairs, etc. to replace the old ones. I think the most useless thing is a teddy bear I bought for my sister, it's very expensive. Back then, when I was little, I didn't have as many toys as she does now. Thereby, I think the item is useless and expensive.
