In some ways, we are very simliar. In others, very different.
We grew up in the same suburb and went to grade schools
in the same district and then the same middle and high schools. We were both "smart kids" and were part of the gifted reading programs and advanced math and computer classes. So essentially, through high school, we had almost identical educations. (Weird thing is we didn't meet until college even though we were only one grade apart, plus we knew all of each other's friends.)
Our parents still live in similar houses in similar neighborhoods, have similar jobs, and make similar amounts of money. We had about the same benefits and hinderances growing up in this sense.
We were raised the same religion, going to church and Sunday school at "sister" churches across town from each other.
We both love working with our hands. If something involves tools - especially power tools - we will actually fight over who gets to do it. He was a little jealous recently that I fixed our furnace after being talked through it on the phone by the furnace company. I am jealous of him because he's going to get to be the one to paint the nursery and put together our new baby furniture. Freaks!
Ethnically and culturally, very different. I'm a Bohemian-German-Polish mix whose ancestors have lived in the Midwest for generations. He's 100% Filipino, born about 10 years after his parents came to the US. Our traditions are quite different, and our parents raised us very differently. Our relationships with our families are very very different.
I'm pretty outgoing and talkative (duh!). He's quiet and shy.
I love being out and about. He loves being at home.
I'm a night owl. He's a morning person.
I like sweet stuff. He prefers salty.
I'm wine, he's beer.
He knows all about politics, religion, music, history, technology, and sports. I know all about medicine, science, psychology, money, cooking, home improvement, and all things Hollywood. We really complement each other in a game of trivial persuit!
I am a hypochondriac. You couldn't pay him to go to the doctor - believe me, I've tried!
