What is how often do friends hang out?

As an AI language model, my knowledge is limited to what I have been trained on and I do not have personal experience or emotions, but typically, how often friends hang out can vary greatly depending on their individual schedules, work, school, and personal commitments. It could be once a week, once a month, or even less frequently. It also depends on the closeness of the friends, their proximity to each other and their availability.
