In 12 hours

In 12 hours John and I shall be meeting our Realtor for breakfast. Afterward we will proceed to our house to do a walk through... then John will sign a lot of papers. Thus, we will have bought a house. I am so excited. Of course I'm anxious as well. Thoughts such as "have we made mistake?" go through my head. We chose a house completely unlike what we were looking for and did not choose a house exactly like we were looking for and was exactly in the area we wanted. What is wrong with us? I hope and pray that it all works out and that we will be very happy with our choice. With the economy being how it is... we may have to stay for a long time.
