Are you familiar with the Meyers-Briggs Personality tests? You can take versions of the test online. I've taken the test a few times in classes and such. I'm pretty consistently INFP, though I strayed to the ENFP side once (I try to be more outgoing than my comfort zone.) Allen recently took a version that was meant to help in his search for what he wants to be when he grows up. He is an ESTJ. There are only two options for each letter. So, yeah we are complete opposites. However it works, we are complete opposities who have been married for 11 years today!
We are currently "celebrating" our anniversary with a trip to a country possibly best known for its chocolate, beer, and waffles (giveaway.) Anyone? Oh, we are staying in the EU capital as well.
