Just how does one sister manage to get so tan while the other is so white? Do they run in completely separate social circles? Perhaps Justine doesn’t have a job and can’t afford the dues at the tanning booth. Maybe they are exact opposites and Justine’s sister likes the outdoors while Justine is an indoor girl. Perhaps it is a fake tan and Justine feels it is unethical to wear something fake. In any event it seems to be another mystery in life that may go on forever and will never be answered. Does it really matter? They are both beautiful girls, tan or not.
