I'm pretty sure my family knows

When I was younger it was basically the only film I would watch. That combined with the large amount of TLK stuff I have now, including a huge TLK wall poster, a ton of sheet music, plushies etc.
My friends definitely know

My TLK super-fandom is basically an inside joke among my circle of friends at school now. A lot of my birthday presents for the past few years have been TLK related, too
This picture is probably the one that holds the most significance for me: my friend Catherine gave it to me for my 17th last June. It was the last thing she gave me before she died at the end of September.
Needless to say, it is very special to me, even moreso now.
