What?
Are you trying to delete your post because it was answered, and doesn't need to be up anymore?
Are you trying to delete the other person's post because you disagree with them?
Are you trying to delete your post because you are embarrased and want to commit internet seppuku?
And how does a bad response enter into it?
Hi: I got a smart answer to a post. Is there a way to delete that post? I have tried to delete the smart answer, but delete key has no effect.
