I also got two phone calls on my cell phone yesterday, neither of them for me. When I got a new cell phone number about a year ago, I didn't realize that it came complete with the ghost of past owners. I'm still getting 2-3 calls a week for "Todd," my deadbeat shadow.
I've learned at least a few things about Todd.
I do want the calls to stop, but it has been sort of interesting piecing together the life of my deadbeat shadow.
