Two years ago, I met this little girl while I was working at Nueva Esperanza primary school in Nicaragua. Her name was Lupe and she was about 5 years old. Every single day, she would come running to the front gates to jump into my arms andgive me a big hug. This morning I walked into the school, and guess who was waiting for me at the front gates ... Lupe ... She said to me: 'Hi, where have you been? Are you going to stay this time?' For some reason that made me extremely happy and very sad at the same time.
