Don’t create “poltergeist” classes.

They’re useless.

These classes have no responsibility and just call methods in other classes.

You can usually replace these classes with calls to the delegate class directly.

Sometimes, developers implement these classes in anticipation of a future need for a more complex structure. This technique is not a good practice. Don’t write code in anticipation of possible future needs. Code for today, to meet the current requirement, to pass the tests.
