You met Candi while standing in line at the Post Office and she noticed you had a Priority Mail letter in your hand.
You explained to her that you had been in an on going dispute with the IRS, and she said she had recently received a notice from them requesting that a payment was due.
You explained to her that she thought there was an error she could fight and inform them of these through your correspondence.
You ended up exchanging phone numbers, and if the relationship extends beyond business, so be it.
