hey there.. i am new here and i dont know if this topic has been here before.. but while reading the books i noticed that hermoine keeps saying that no one apparate or disapparte inside hogwards but i have noticed that the house elfs like dobby apparate within hogwarts and also apparate into hogwarts frm out hogwarts as well..
and in the 6th book when ron fails his appartion test he also mentions that he wish he could appate like the dobby.
