Now I feel so vulnerable…
This was a popular scam in Japan for a while – grandparents would get a phone call from a panicky-sounding young man who would just say “It’s me! It’s me” and the grandparent would venture a name (“Shin-chan?”) and they would be off and running. It was happening so much that it came to be called the “It’s me, it’s me” scam (in Japanese, oh-reh, oh-reh). I think it got too well known and the fraudsters moved on to something else, because I haven’t heard much about it for a while.
My 90-yr old Aunt got a very similar call. Aunt Bea, this is your nephew “Brad”. I’m in jail in Mexico and I need money to get out.
She replied, “Call your mother”, and hung up.
Decades ago - I think before scams were so common - I had a couple of calls like that.
The first was at around 2am, in the early 1980s … before the internet, before cell phones, just a call on what we’d now call a “landline” but in those days was just your phone. A hopeful voice said, “Carol?” and I cautiously said … “yes?” (My name was in these weird dead tree books we used to publish called “phone books” so I wasn’t exactly revealing secret info.)
The caller, a male, said, “it’s Mike!” and when I said, “um… Mike who?” proceeded to weep copiously, bitterly castigating me for forgetting MIKE, you know, MIKE!!! (At the time I knew two people named Mike, but was smart enough not to say “Mike Smith or Mike Jones?” but rather to wait for the caller to properly identify himself as one or the other.)
Anyway, I finally had to hang up on “Mike” despite his plaintive cries and refusal to go beyond saying “it’s Mike … you KNOW who it is, it’s MIKE!”
A second, similar call came a few years later, in which my “Aunt Ruby” wept at the fact I didn’t know her.
At the time(s) I thought they were drunk dials or scams of some sort. But now I know … they were CALLS FROM THE FUTURE!
As decades have passed, I hope to meet “Mike” and “Aunt Ruby” any day now. 
I woulda partied with this Cowboy!
