I am writing to express my enthusiasm to join your family and care for your kid. I have some justifications to choose this job. The first point is that I am an extroverted person and I can adapt to new people very quickly. Another ground is that, due to having several nieces and nephews, I am able to communicate with children and have a good relationship with them. Moreover, I have studied a lot of books and articles about babies and teenagers and learned how to deal with them.
