Your reasons for dropping are personal, so I don’t need to know them. All I ask is that you just notify me that you are dropping (the Registrar won’t let me know), so that I can remove your name from my record and don’t have to chase you to see if you’re doing okay. If I don’t hear from you for a while, I’ll get worried and I’ll spend time trying to contact you. In short, don’t tell me why you’re dropping, but please respect my time and effort by letting me know you that are.
