Considering my age: If I have not outgrown it yet, I never will.
I have adored TLK since I was 8, and although I have had periods of low intrest, I have never completly stopped loving it. I know I will certainly never grow out of it, it’s simply not possible. I consider myself to be fairly childish, and I love classical Disney movies. In my opinion, you can never grow out of them, or be too old for them.
TLK is so special and dear to me, I will never stop loving it regardless of how old I am.
