I'm switching service from my phone to Col's old phone because he has a shiny new one now. So in order to do this, I have to give them some information on the account, including the last 4 of my dad's SSN. So I call him up and the following is our conversation:
"Hi, how are you?"
"I'm great. How's your day going?"
"Alright. What about you?"
"Fine. I'm switching service on my phone so I need the last 4 of your social."
"I'm switching service from my phone to Col's old phone so I need the last 4 numbers of your SSN."
"Wait. Who is this?"
At this point, I look at the phone to see what number I'd dialed. Wrong number. I'd messed up the number by one digit. I panicked and hung up. I'm sure the guy thought I was some scam artist trying to get his social security number.
What's crazy is how he sounded enough like my dad that we chatted a bit... evidently I sound like his daughter as well.
I'm still laughing.
