The boy is 18 and the girl is 9
Well, if you're three years older than your sister now, you must be feeling pretty ancient. In 20 years, your sister will be twice as old as you are now, which means she'll be catching up to your current age. So, if you're feeling old now, just wait until your sister starts lapping you in the age race.
