Younger
Look, you are getting any younger. I mean, that's how we age—downward. Therefore, perhaps I should say, you aren’t getting any older. The time to seize life is now—so we may as well get married. Do you want to be single when you're 5? Then who's going to change your diaper? Although, even if we do get married, I won’t be changing any diapers, because I'll be a similar age to yours then, and thus incredibly fussy and uncoordinated. Still, what do you have to lose—except your language skills, your legal ability to drive and vote, and your potty training?
