去超市(Go to the supermarket)
i went to the supermarket the other day with 10 yuan. i was a bit hungry, so i decided to buy a small pack of cookies which cost me 4 yuan. after i ate them, i was still hungry, so i decided to buy a small bag of potato chips which cost me another 3 yuan. after i ate them both, i was no longer hungry.
　　however, i was very thirsty and wanted to buy a large bottle of milk to drink, but i didn”t have enough money left because even a small box of milk would cost me 2 yuan and i needed 2 yuan to pay the bus fare. so i gave it up at last.
