I have been aggravating my wife that I have finally "Mastered" something. I also kid her because she has a bachelors in nursing and I have a Masters now. Though she has 4 years of experience it still eats at her when I rub it in. She is also in CRNA (doctorate) school right now ... so she tells me to live it up for 2 years till she finishes.
I love driving her crazy.
