What am I doing wrong here?

I am being asked to override the Equals method. This is based on the C# video called Object.Equals. I followed the override format that was in the video almost exactly, just changing where the video said Point to VocabularyWord in this exercise. However it keeps telling me that it still returns false when the two words are the same. What am I missing here?

VocabularyWord.cs 
using System;
namespace Treehouse.CodeChallenges
{
    public class VocabularyWord
    {
        public string Word { get; private set; }

        public VocabularyWord(string word)
        {
            Word = word;
        }

        public override bool Equals(object obj)
        {
            if(!(obj is VocabularyWord))
            {
                return false;
            }

            VocabularyWord that = obj as VocabularyWord;

            return this == that;
        }

        public override string ToString()
        {
            return Word;
        }
    }
}

You're really close, but in your code both "this" and "that" represent VocabularyWord objects. The instructions ask that you compare "the words of two VocabularyWord objects", but the code here is directly comparing the objects themselves.

Thanks! I changed that one line to return this.Word == that.Word and it worked!
