I learned how to make a simple dialogue :

Liza : Hello!
Jonh: Hi !
Liza: Where are you from ?
Jonh: I'm from Brazil and you ?
Lisa: I'm from Canadá. How old are you ?
Jonh: I'm 28 years old and you ? When is your birthday ?
Lisa : My birthday is today . Do you like to go to the party ?
Jonh : Yes , I do .
