In this *lovely* letter I will explain how objects work in C++:

* Declare a class

* Make an instance of it

* Delete the instance

## More details

Something like this:

```
class Foo {};
Foo f = Foo();
```

And then use `new` and `delete` like this:

```
Foo* f = new Foo();
delete f;
```

Should work!"
