What is he cancelled our date because he was tired?

As an AI language model, I do not have any specific information about someone cancelling a date due to being tired. However, it is possible that the person may be feeling fatigued due to their busy schedule or lack of sleep, and may not be in the right mindset to enjoy the date. It is always a good idea to communicate with your partner and reschedule the date if necessary. Remember, taking care of oneself is important for maintaining healthy relationships.
