Determining the opportune moment to slip away can be a challenge, but there are reliable guidelines to follow. Timing your exit hinges on your parents' sleep schedule. If they tend to stay awake late and rise early, it is wise to wait around 30 minutes to an hour before making a move. In the event that they are sound asleep with no risk of potential distractions, such as unexpected visitors or their phones lighting up, it might be best to wait until that point.
