Paul thinks this was his 16th birthday but it could've been his 15th he admits.
Not sure on exact date but sometime when Gwenny was aged 16 she got her wisdom teeth removed. She remembers being very uncomfortable and gagging with all sorts of padding down her throat as she was recovering.
It was fortunate for Paul that Gwenny lost a bit of her wisdom so he could talk her into marrying him when he did.
