You bought a camera on sale at a store, but it didn't work right. The salesclerk said, "We can´t do anything about it."
You were not happy with the grade you got in an important class.
You sat on a park bench that had wet paint on it. You ruined your clothes. There was no "Wet paint" sign.
You checked you bank statement and noticed that there was a deposit of $ 1,000. You didn't make the deposit. You´re sure it was a bank error.
Your next-door neighbors borrowed your vacuum cleaner. When they returned it, it was damaged.
A friend gave you an expensive vase for your birthday, but you didn't really like it.
I guess I´d take it back to the store and exchange it for something else.
I think I'd make an appointment to see the instructor to talk about it.
Maybe I´d ask them to repair it.
I´d probably wait until the next month to see if the mistake is corrected.
I guess I'd write a letter of complaint to the manufacturer.
I'd write a letter to the city council and ask them to pay the damage.
