I
love to get mail! Anything works as long as it isn't junk mail (or stuff from colleges that I've been getting since the PSATs

--I call it my fan mail

). Letters are my favorites, especially long ones.
I save all of my personal letters and cards. I love to look through them later. Letters are especially important on my mom's side of the family, and my aunt just compiled a huuuge book for my grandfather of all of the letters he's sent her throughout the years. It's beautiful! So many memories and funny tidbits...

Weirdest mail-related occurrence that comes to mind: When I was younger, I went to this one camp for two sessions in a row, and my friend from the first session promised to write me a letter. When I got it, the envelope was in a plastic mail service bag that said something like 'we're sorry, your mail has been damaged in transit' and the envelope was kind of beaten up. There were several lumps inside that turned out to be a couple of pieces of candy (something like a tootsie roll and...whatever), but she said something like 'enjoy the candy necklace' (she was very specific about the contents, but with no tootsie roll references).

The flap on the envelope did look altered...I remember wondering why they had opened my letter (bomb check?

) and what had happened. "Phew, no bomb--hey, a candy necklace!" "Let's replace it with these nasty tootsie rolls. She'll never know." Looking back, they probably thought it contained some type of drug, but never mind. Needless to say, I never ate the candy.
