This is Mary.
This is Mary's husband.
One day, she goes out shopping.
And goes to the store.
And then returns home.
"What did you buy?"
"I bought a hat, pants, shoes, and gloves."
"But where are they?"
"Oops! I forgot them at the bus stop!"
The next day she goes out again.
And goes to the store.
And then returns home.
"What did you buy today?"
"I bought pants, a shirt, a hat, and shoes.
"But where are they?"
"Oh no! I left them on the bus!"
The next day she goes out again.
And goes to the store.
And returns home very late.
This time she has all her purchases.
"What did you buy today?"
"I bought shoes, a hat, socks, and pants."
"But why are you home so late?"
"I spent so much this week that I didn't have any money for the bus. So I had to walk home!"
