 :::::I don't see the word stupid in any of his comments.  I think you have an issue with feeling that other people think you're stupid.  Perhaps someone has told you this in the past.  No one is calling you stupid and no one has engaged in a personal attack on you.  You must admit that you have been made some grammar mistakes.  It's entirely appropriate for someone to point that out to you.   Mufka    "
