You don't have to admit it!

I stopped by someone's office today. Someone I have known for 6 years. I've been to his house and I see him most weeks. And today I learned that he didn't know my name. For 6 years he has been calling me 'Nita' and I never noticed. So, today, when he wrote 'Nita' down, I told him he misspelled my name. He had a golden opportunity to play dumb, say "where?", and just fix it when I told him. I never had to know. That may technically be dishonest, but I would'nt've fessed up. I'd've pretended I knew his name all along and just spelled it wrong.
