One night, when I was eight, my mother gently asked me a question I would never forget. "Sweetie, my company wants to1me but needs me to work in Brazil. This is like your teacher telling you that you've done 2 and allowing you to skip a grade(跳级), but you'll have to3your friends. Would you say yes to your teacher?" She gave me a hug and asked me to think about it. I was puzzled. The question kept me4for the rest of the night. I had said "yes" but for the first time, I realized the5decisions adults had to make.

For almost four years, my mother would call us from Brazil every day. Every evening I'd 6wait for the phone to ring and then tell her every detail of my day. A phone call, however, could never replace her 7and it was difficult not to feel lonely at times.

During my fourth-grade Christmas break, we flew to Rio to visit her. Looking at her large8apartment, I became 9how lonely my mother must have been in Brazil herself. It was then 10I started to appreciate the tough choices she had to make on11family and work. 12difficult decisions, she used to tell me, you wouldn't know whether you made the right choice, but you could always make the best out of the situation, with passion and a 13attitude.

Back home, I 14myself that what my mother could do, I could, too. If she15to live in Rio all by herself, I, too, could learn to be16. I learnt how to take care of myself and set high but achievable17.

My mother is now back with us. But I will never forget what the 18 has really taught me. Sacrifices 19in the end. The separation between us has proved to be a 20for me.
