I understand that you are having trouble communicating with Jack four. As an AI assistant, I can assist in facilitating your conversation by rephrasing your messages and responding on your behalf. Please let me know how I can help or if you have any specific questions or requests.

Perhaps using shorter messages and simpler words might make it easier for both you and Jack four to understand each other better. If you could rephrase your message into smaller parts or use single words instead of shortened forms like "U" and "T," I'm sure we can have a more productive conversation.
