Yes, it makes sense. As an adult at 23 years old, it's entirely normal to have a desire for more independence and privacy in your life. You may feel that you don't need to share every detail of your plans or activities with your parents, as you are now capable of making your own decisions and managing your own time.
Telling them when you'll be arriving back is a considerate gesture, as it allows them to know when to expect you and ensures they won't worry about your whereabouts. It's a way of maintaining open communication while also asserting your independence.
It's common for parents to feel a mix of emotions when their children start becoming more autonomous. They may feel confused or concerned about the change in communication, especially if they were used to being more involved in your day-to-day activities when you were younger.
It could be helpful to have an open and honest conversation with your parents about your feelings and the reasons behind your desire for increased independence. Reassure them that you love and appreciate them, but you are now at an age where you want to take more responsibility for your decisions and actions.
Building a healthy adult-to-adult relationship with your parents is a gradual process, and clear communication can go a long way in bridging the generation gap and fostering understanding. Letting them know that you value their advice and input but also need space to grow as an individual can help strengthen your relationship and ease their concerns.
