Peter’s dad comes from the UK and for some reason decided to move to Australia. Five months living there, he lost one of his eyes because of magpies.
When Peter was younger, his older brother Jarrad convinced him to ask his dad if he was a pirate. His dad didn’t want Peter to be scared of birds by telling him the truth (even though it wouldn’t matter since he’d end up hating birds later on in life anyways), so he said he had to take care of his eyes or else they had the risk of falling out.
It wasn’t fun for Peter when his family learned he needed glasses since this scared him, making him think his eyes would fall out when he was an adult. And his mom wasn’t happy with his dad for telling him something like that.
