Thanks for the info and one last question, I sent out a note andp icture inside an enveloped that fit it. On the front though, It had lines where you write the persons adress and my adress. Will that decrease my chances of getting it back?

Both.

By the way, I sent the photo and letter out on October 12th.

When I when't to the post office, I sent a photo in an envelope, but I forgot to write "do not bend" on it. However, the girl at the counter put a stamp on it herself. Is that okay?
