The department store is good
But you need a lot of food.

Now you leave it for the street.
And your friend goes to the shop
With a basket - hop, hop, hop!
First he buys some bread and meat -
Meat is what you really need,
Eggs and butter, milk and jam,
Orange juice, a sausage, ham.
In the basket that he carries
Are bananas, plums and berries.

A department store is big,
Shop assistants are so quick,
Many things are in the shop
From the bottom to the top:
Belts and handbags, leather gloves,
Stylish dresses, jeans and scarves,
Metal buttons, buckles, thread,
A panama and a hat,
Silver bracelets, golden rings
And a lot of hairpins.
