There are bold letters in both of the letters, the first one has 'H' and 'E', and this one has 'L' and 'P'... HELP
I didn't notice that before. Good find. Maybe this is more urgent than I thought...
There is also / and \ marks in the letters, I think the words between them are a message. This letter says \you don't remember me/ and /didn't want this\. On June's letter it said /it was in the treehouse\
Does the VP64 in the background trigger any memories? This picture looks like it may have been taken when you were all still friends.
The slash marks might be important. The information in them does seem significant, but I'm not sure how to decipher it yet. I also don't want to say I'm sure of anything until I can contact Erin (though I'm beginning to give up on her). I just have a nagging suspicion that she may have gotten one of these letters too.As for the VP64, I have no clue. If it comes up more in the future, I'll do more research. I can't remember any significance to it, but my judgement can't be trusted here as my memory is so clouded.
