Объяснение:

Usually my mother always sends me to the grocery store. We make a list of everything you need in advance, because everyone loves to eat. My dad loves meat, my mom and I choose dairy products, and my little sister always asks for sweets and chocolates. My mother and I make a list of all the necessary products, and if our elderly neighbor needs something, then I usually shop for her too. Here's a list, and I'm getting dressed quickly. I approach the store in a good mood, because I will buy something tasty for all my family. I look carefully at the shelves, suddenly something new has appeared. Everyone usually loves to buy with discounts, so you can save a lot of money, and they will never be superfluous in the family budget. First of all, I take a loaf of bread and sweet buns for tea. Then I buy my dad's favorite sausage, fish that mom will cook for dinner, and a lot of all kinds of vegetables, yogurt for my mom and me, and candy with bananas for the baby. I pay for the goods and put everything in my bag. Now it remains to walk to the house and give everything to my mother's hands. I helped my mother again and bought everything for dinner and afternoon tea. This store is close to home and we always buy groceries there.
