You don't have to apologize for calling the character "black" any more than you have to apologize for calling a character "white." You're being really silly. If you called him African-American, that would be really stupid.

The story is OK, but you need to punctuate correctly and provide more detail without overusing adjectives.

I really liked this, I hope you continue. Punctuation would have made it more enjoyable, however, I enjoyed the style and subject and I feel you could make this into a good short story that resolves what it has begun.

Why don't you use quotation marks?
