Glad you guys have arrived and got the house and important stuff sorted!
I reckon you are probably feeling what most people would feel and its the bit (other than goodbyes) i fear the most when the time comes. As you say you have been so busy with the whole move and getting carried along with the journey of it all, that when you have 5 min to sit down and take it in the enormity of it, it smacks you in the face. And as you previously said theres no fanfare of trumpeting procession playing welcome to oz at the airport, just good ol passport control. It takes most of us a heck of a long long time from the thought of moving to actually landing Daniel and it takes up a huge part of our lives and something we plan for ages so when you get there and everyone is just going about their lives as normal its no wonder you would feel a little "flat". I know this is different but i mind losing my grandma who was like my 2nd mother and the next day driving past morrisons and seeing people shopping and thinking how are you just getting on while my life is standing still? i imagine the arrival in oz maybe slightly like that?
Either way im positive you will make a great new chapter in life for you and your family Daniel, especially once you get stuck into the new church and become more intergrated with the community,
keep us posted and best of luck
