Doing the shopping
Shopping usually means going to some place to buy something. It is a part of our life and we have to accept it whether we like it or not. There are people who hate shopping, so they usually make a list of the things they need, run through shops and buy them. There are people who go from shop to shop choosing goods at a lower price. For some people shopping is a hobby; they love shops and they can spend hours in large shopping centres. Such people are called "shopaholics" because they sometimes buy things which they do not need and it is like an addiction.
My family usually does the shopping at weekends. My parents work too hard, so they do not have enough time to do the shopping during a week. On Sundays we go to a supermarket and buy food for the whole week. I don't like supermarkets, because there are crowds of people there. You can buy anything in such supermarkets: poultry, meat, seafood, dairy products, etc.
There are a lot of different shops in my city, both expensive and cheap and everyone has a choice where to go. I prefer going to a big shopping centre not far from my home where there are a lot of shops and a food court. There are clothes shops, shoe shops, a florist's, a chemist's, an optician's, a jeweller's and many others. I usually walk there with my friends doing the window-shopping.
When I need clothes or books I do the shopping alone. My favourite bookshop is just in the centre of my city. I can spend hours inside looking through new books. I also like shopping when I need to buy presents for my family or friends. Sometimes my friend helps me to choose presents. She is a nice girl with good taste and she knows what would be a nice present for my family.
In childhood, I used to like shopping because I felt grownup, but now I see that it can be quite boring and time-consuming. However, we have to go shopping because we need food and other things that are necessary for our life.
