Getting on a plane equatting to a sperm or egg travelling to the womb to meet up with the other.
Once together, the fetus gestates in the womb for the next nine months. Much like landing and trying to get through customs and immigration.
Once born, you gaze upon the new world with wide eyed wonder and amazement at everything. Its all new and you cant help but point at things you've never seen before. With reckless abandon you scurry over to the first thing that catches your eye.
