When two people get married they are bringing together all the many different aspects of who they are to a whole new union, a new family. They each bring in different aspects of who they are, and a big part of who they are is how they were raised and the habits they have.
For example, when we first got married I thought it was strange that Trevor insisted on putting the salt and pepper together on the top of the stove. It didn't really bother me per se, but I thought it was an odd place to put them.
One time we were washing dishes, and we had just opened up a brand new sponge. Trevor accidentally dropped it on the floor, and insisted that it was now filthy and needed be thrown away. I was raised that a "little dirt don't hurt" and thought this was ludicrous, I mean, it was a BRAND NEW sponge that you use to wash dirty dishes? I digress...
Habits, traditions, ideals - they can be an interesting part of shaping a marriage and family - and I am really excited to see how ours shapes up :)
