What does the agency always
1. You will become an extended part of a new family. If every domestic help were treated as a family member, the world would be more beautiful.
2. Host family offers room and board. I was sleeping in a children's bed. I'm so skinny (and short) that they should have offered me a crib.
3. You are taking on new responsibilities, but you will spend time with a wonderful family. Seriously? Once host mum told me that I'm straight-laced and the only hope for me was to have a casual sex.
4. If you're keen on studying foreign languages - it's a perfect job for you. My dream was to speak Spanish fluently. Host kids didn't have a smattering of English so host mum called the agency to change the contract. So I had to speak English all the time.
It was an unforgettable experience, but I didn't develop life skills or make friends with many people. I just explored Spain and taking care of children almost leads me to a crime :D
