What physical characteristic would you change about your significant other?

His skin - note that I didn't say skin COLOR. I like his color - but my significant other does NOT take care of his skin. He likes working on cars - and worked on cars a lot in the past. So he's had oil spills all over his arms and hands and some of it seeped through his fingers. But he only washes with soap and water!! So now his skin is always dry - and if I don't remind him to use lotion, he doesn't use it! And I always say to use gloves when he's working on cars - and he just goes on and on that he's got weird hands that don't fit in ANY of the gloves that they have anywhere. Blah blah blah... Anyways - I'm on a mission - to make sure this boy takes care of his skin from now on. I ask EVERYDAY -did you use your lotion today? =P
