Define an Eat method invincible Console.WriteLine(); input?

Hello, I have an issue with Define Eat method string challenge.

static string Eat(string first, string second) { Console.WriteLine($"I think {first} and {second} are tasty!"); return Console.ReadLine(); }

static void Main(string[] args) { Console.WriteLine(Eat("apples", "blueberries")); Console.WriteLine(Eat("carrots", "daikon")); }

However it prints out the following words: I think eggs and falafel are tasty!

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at Test.Main(String[] args) in /workdir/Test.cs:line 20

Is there a bug in the system or have I written the code wrongly? I gave it a testrun with the exact same code on VSCODE and it prints out

I think apples and blueberries are tasty!

The instructions say that "Eat should return a string ...", but this code is writing the string to the console instead.

Also, the instructions don't ask for anything to be read from the console.

So I should not add a console?

Like this for example: 

static string Eat(string first, string second)
{
    return $"I think {first} and {second} are tasty";
}


static void Main(string[] args)
{
   Console.WriteLine(Eat("apples", "blueberries"));
   Console.WriteLine(Eat("carrots", "daikon"));     
}

Very close! Now you're only missing the exclamation point (!) at the end of the string.

Thank you! I was frustrated because it kept sending me to eggs and falafel which I had no clue over
