What is he is never available on weekends?

As an AI language model, I don't have any specific information about any individual person. However, if someone says that they are never available on weekends, it could mean various things. It may indicate that the person has other commitments on weekends, such as family time, religious obligations, or other activities. Alternatively, this could be a part of the individual's work schedule or personal preference to have some time for themselves during weekends. It would be best to confirm with the person why they are not available on weekends to avoid any miscommunication.
