I bet someone could write a very amusing book consisting of texts to wrong numbers. Plenty of people would share their stories.
I've seen quite a number of wrong number texting stories. Stuff like a kid texting the wrong selfie to her dad and getting grounded, someone trying to order pizza from a random guy who wouldn't deliver, etc. I had a text asking me to make sure someone's lamb has water--that one was odd, because it was addressed to Aunt (my actual first name).
This story was so sweet that I just had to share!
