Today, I received a mail without a return address...and when I opened it, IT IS RACHEL'S AUTOGRAPH!!
I was so surprised! I was wondering, "When did I send a letter to her?!"
So I checked back my record book and found out that I actually sent a letter to her in July, 2012!
It was so long ago that I forgot I sent a letter to her hahah!

Sent: 7/9/12 (LOR only, she was kindly enough to send me her picture!)
Received: 2/5/13

No envelop.
