Reason # 123:
I couldn't be farther from you and still feel your inferior and superior vena cava sending de-oxygenated blood into your right atrium, which pumps it through a tricuspid, atrioventricular valve into the right ventricle, where the blood is sent to your lungs and, through gas exchanges in the alveoli, becomes oxygen-rich and returns via the pulmonary veins to your left atrium, where it is pumped through a bicuspid atrioventricular valve into your left ventricle, after which that oxygen-rich blood is pumped through a semi-lunar valve straight into your aorta, to be delivered everywhere in your body but the lungs.
You knew of course that your father's inferior vena cava is dislocated reflectively from other people's, but his heart is in the right place.

I did know this. That doesn't correspond with anything I learned in bio, but there you are.
