what can i say in video to host family

I really want to be an au pair, because I love travelling. It's My the biggest dream is to visit the USA. I'm convinced that I will be a good nanny for yours children. I work as a teacher in kindergarten. I'm working with kids who are between 3 and 5 years old. I have also three cousins. We spend a good (or say "an enjoyable") time together and have a lot of fun. I like spending time with children, teaching them new things and playing with them. I hope you enjoy this video. See you soon.

This is very good!
