Relocating to a new place is always scary. Especially when you are crossing oceans.You are basically in a new world, with new cultures, with new people, with different beliefs, with new perspectives to life and work. Not to mention the new stares (Now I know how animals in a zoo feel like. I don't think I will ever visit a zoo again in my life). The occasional relief when you see someone from your own habitat.
Its just a matter of days. Human beings are wonderful creatures. Soon the new place becomes the new habitat.
