Suspicious

I got an email from a person I rarely get anything from.  It said "Touching basis". This from a woman who speaks fine English?  Sometimes, I would trash that and forget it but I like that woman.  I wrote back and said that it was rare to get something from her so could she write something to convince me the source was genuine?  I received a photo of her husband's driver's license with the message "Now I have proof you."  I explained my suspicions to my wife.  During the conversation, I realized I had not compared the email address with my record. Oops!  Didn't match.
