Yes, I think you do have an NDad because he exhibits all of the traits you discussed, which MY NDad also exhibits.  The talking is the worst.  I think it's hilarious that my dad can talk for 15 minutes straight about anything to my mom (who is his worst victim), but can barely speak when directly confronted about an important issue.  I may never recover from being raised by an NDad, but I hope you can hang in there.  Take care of yourself.
