HALP Prog question

Create an interface, "IBendable", with one method, "Bend".  Create two classes, "Spoon" and "Arm", that implement "IBendable". "Spoon" will also have an "Eat" method, and "Arm" will also have a  "Raise" method.  Each of these methods prints a message indicating its function.  Write another class with a "Main" method, declaring two objects of type "IBendable", one a "spoon" and another an "arm".  Call the "Bend" method.

help me pleeeeeeease

Here is my code:

using System;
class Arm : IBendable
{
    public Arm()
    {

    }
    public void Raise()
    {
        Console.WriteLine("Raising arm up.");
    }
    public void Bend()
    {
        this.Raise();
    }
}
class Spoon : IBendable
{
    public Spoon()
    {

    }
    public void Eat()
    {
        Console.WriteLine("Eating from the spoon.");
    }
    public void Bend()
    {
        this.Eat();
    }
}

class Prog6_18
{
    static void Main(string[] args)
    {
       
        Spoon childsSpoon = new Spoon();
        Arm childsArm = new Arm();
        EatFood(childsArm);
        EatFood(childsSpoon);

    }
    public static void EatFood(IBendable a)
    {
        a.Bend();
    }
        public interface IBendable
        {
            void Bend();
        }
    }
