 There are two types of people in a relationship, be it a romantic one, a platonic one, or a parent-child one. There's the person who doesn't wear sunscreen and the person who nags the person who doesn't wear sunscreen. I am usually the latter, which is quite a role because when you're at a picnic or the beach, you're supposed to reapply sunscreen every couple hours, sunscreen that's often greasy and messy and hard to rub in.
