What is he disappears on weekends?

As an AI language model, I cannot give information about specific individuals without their consent. However, generally speaking, if someone disappears on weekends, it could mean that they may be spending time with friends or family, engaging in hobbies or recreational activities, traveling, or simply taking time away from their usual routine. It could also be possible that they may be struggling with personal issues or may be intentionally avoiding social interaction. Without more information, it is difficult to determine the reason for someone's weekend disappearance.
