     I spent three months volunteering with Volunteer Bolivia(玻利维亚). It was sometimes

annoying, scary and difficult, but also life-changing, satisfying and amazing. Because I had

studied Spanish for a couple of years before I went out, I had just one week of classes at

Volunteer Bolivia.

     Living with a family also helped my Spanish greatly and I felt immediately like one of their

daughters. We were good friends from the beginning of my time there and I was looked after

very well. I still had a lot of independence. The Volunteer Bolivia centre, with its cafe bar and

cultural talks, was a meeting place for all the volunteers and I met some wonderful people

from all over the world who were doing the same as me------giving something of themselves

to a country which needs so much.

     My job was in a caring centre for prisoners' children from the Cochabamba prisons and

from the very (恰好的)start I felt welcomed and needed. There I met some inspiring members

who put so much of their heart into caring for those children who maybe had no one else to

love them. Not only the work itself was very hard but at times it was emotionally demanding,

especially sending a group of two year olds back into the prison at the end of the day. Despite

all this, I learnt a lot through the experience and now I'm more aware of the problems faced

daily by many people in South America. The centre has very limited funding (资金)so they

depend heavily on the work of volunteers, and any time people give is very valuable to them.

     Since returning to Britain I have kept in touch with the people I worked with and I'm trying

to support them as much as possible. Volunteering through Volunteer Bolivia has changed my

life and is an experience I will never forget.
