In book 1 Dumbledore gives Harry the invisibility cloak of his father as a Christmas present, explaining what it is and giving advice on an anonymous note. (It is also emphasized in the book that the note is indeed anonymous rather than implied as in the movie).
Why did Dumbledore choose to stay anonymous in this case?
I can neither think of a reason why he would nor find any references on the matter. Thanks for your insight in advance!
