We guess there's a reason they call it snail mail!!
Little Joanne Selby had always made an effort to send her grandmother postcards whenever she traveled, so when she and her family went on vacation to Nefyn in Wales, she made sure to send a letter!
The only problem is her grandma never got the letter, and that's probably because it wasn't delivered until more than 30 years later!!!
Sadly, Joanne (who now goes by Joanne Flemming) says her grandmother passed before the letter ever got to her. However, she says she's currently living in her old house and was SHOCKED when they letter turned up on her doorstep:
