Life correlations

I'm going to the EMBO conference on Nuclear Receptors. Last time I went - four years ago - my wife was pregnant and in the middle of the last talk phoned me because of the labor contractions. My house was 100 km long away, and I come back in time.
Now, my wife is once again pregnant and tomorrow I'm taking the flight. Delivery is expected on February. Hopefully, it should be easier this time.
