I left my mom's book (with stu's letter inside it!!!) on a coach in France :X It sucked extra because I hadn't finished reading it yet

I am not an object,
Something you throw away.
I am no piece of junk
Left on a stationary train.
Won't you get a message
To the one that's gonna set me free?
Tell her to hurry, tell her to recognize me
'Cause I'm beginning to believe
That forever I'll live on a shelf
Of the lost and found.
