“Mike used to say: how life happens is a letting in. When he was trying to convince me about the baby. He said every time it was an act of ridiculous trust. The sperm buries itself in the egg and stops being able to move. The egg lets down all its defenses and allows a foreign object in. That’s how it happens, every time. An absolutely unjustified leap of faith. Open up, let in, be let in. Opening is dangerous, every single time. But that’s how we’re here.”
