This is quite a fun little piece to camera as two friends - Marta Martin and Saida Benzal are munching their way through a bag of seeds whilst one suggests to the other that her boyfriend is having an affair with someone called "Pi". She reckons it's "Pilar" but he assures her it's Pi (π) - as in 3.14 - because that's the infinite nature of his love for her. They both know that's nonsense because there are only numbers 0-9 and, as she knows from her bright yellow hoodie - π is an interesting Chinese character! I'm not sure he'd be terribly worse off if she were to dump him! A little knowledge is a dangerous thing.
