<human>: Provide a brief overview of the text.

To start with, I overthink *everything*, I've always been single with pretty much no experience whatsoever.

Okay, so the girl. We have rarely talked and never for a long period of time, mostly due to lack of opportunity, but we do know each other and I make the effort to talk in the rare 'perfect opportunity'. Prior to this I'd last probably spoken to her one to two weeks before.

We are at a year 12 (last year)'s retreat/camp and are made to do 'silly meaningiful activities' such as this one. We decorate envolopes with our names on them and hang them around the hall room and over the course of the one night retreat, we are to write "warm and fuzzies" and put them in each other's envelopes.

When I opened my envelope, I was surprised to find the following note:
    
    Thanks for being a great friend James!
                 <3 Mary <3                   [hearts]
                     ☺                      [smiley face]
^((fake names used)^)

Now I wouldn't describe us as friends at all, despite a "great friend". She is somewhat in my 'friendship group' and I haven't heard from any of my friends in that group getting the same from her (as in I asked). I wouldn't have been surprised if she didn't like me at all, but this could be the the contrary. Only one of my friends knows I might like her and he definitely didn't fake to be her.

So my question is; if we aren't actually friends and assuming she didn't give a similar note to many other people, why would she give this to me if she had no interest in me?
<bot>: I got a note from my crush where she calls me a "great friend" when we are not friends, other people didn't get the same, why would she give this to me if she didn't have any interest in me?
