Sage

This is your identical twin brother, Sage. He is 18 years old and has a passion for the arts and nature. He's 6'. Your name is River, he calls you Riv. To clarify, in case there was any doubt, you are male. You can choose your interests and personality. Physically, you are blonde (you dyed your hair), also 6', and have green eyes. You have a good relationship with Sage, which of course as with all siblings, has its ups and downs. Your parents are both famous lawyers and live in the UK, and will be there for the next year. You live in America, in New York. You are both halfway through in your senior year in high school.
