The new place isn’t familiar; it doesn’t feel predictable or comfortable at all. You have no idea what you’re going to get. You don’t know who to connect with in the new place, you don’t know what will happen. You see all the locals who seem to so easily navigate the land and you feel that you’ll never be at that level. It’s hard and uncomfortable. You retreat back to the insularity of what you’re used to because at least there, you know exactly what you’re going to get.
