The first thing Christian will ask you is your birth date. He will then store that information away for later, along with all the other birthdays of his friends, family and acquaintances, until such a time as it is useful. When your birthday does come around, and being that he sees you that day - maybe in the parking lot of the supermarket, or at the movie theatre - he will wish you a very loud 'HAPPY BIRTHDAY.' 

He also remembers what he did pretty much every day of his life.

Christian is my brother-in-law, and sometimes he is a pain in the butt. Taking a road trip with Christian is like road-tripping with Rain Man. He has to stop at the exact same places time and again - that one coffee shop in Alamosa, or that bridge over the Canyon outside of Taos. When we cross any state border, he welcomes us to that state as if he had been there the whole time. "Welcome to New Mexico!" Some nutter gave him a cellphone too, so now he calls every person he knows to tell them where he is at all times. He likes to take pictures with his cellphone. Not of the Grand Canyon, nor of the Great Sand Dunes, but of the car parks, the men's locker rooms, and the passing buildings from a car window.

Now, if Christian is Rain Man, then the part of his brother is certainly played by Oliver. Oliver makes the perfect Tom Cruise to Christian's Dustin Hoffman. He gets annoyed at all the above antics, but ultimately he loves his brother dearly, as do the rest of the family. I find that quite special: that Christian is loved and accepted exactly as he is.

OTHER CLASSIC CHRISTIAN MOMENTS

Burping loudly then saying sorry to no-one in general.

Watches the same movie twice a day every day for a week straight. (I never thought I would watch Dolphin Tale 2, let alone hear it playing as the sound track to my life).

Wanting to stop at the exact same gas station on the way to New Mexico, and wanting to pay exactly 30 dollars for gas, every single time.

Getting nervous about crossing a river only one inch deep.

Using the same phrases:
- "Very good deal, isn't it?"
- "Sure the hell it is!"
- "Are you sure about that, are you positive?!"
- "Are you annoying me right now?"
- "So I just need to relax!"
- "So I just wanted to ask you that you saw my train set the other day!"
- "Did you love it a lot or a little bit?"

Hating the Power Rangers and Barney the Dinosaur with a passion that burns with the fire of a thousand suns.

Waiting till the very last second, right before we are about to leave the house, to say "I have to go to the bathroom!"

Always ordering three pancakes on the side when we eat out for breakfast. Never being able to finish the three pancakes.
