I want a quarter to buy a gumball, so I'm going to get one from my brother's coin collection.
Why? How do you plan on getting one stealing it?
I'm going to trick him into giving me one
Don't trick him. It's wrong to steal and you need to get your own quarter instead.
But I'm so hungry.
A coin collection is really important to some people, you can ask your parents for a normal quarter. If you spent a quarter it could have been worth much more than face value.
