Hello! My name is Adriana. How're you?
Nice to meet you!
Bye, see you soon!
I'm very worried because I've a lot work to do.
I usually use the internet to search, to send and receive emails, to access the facebook, to make work and others.
Hello, please could I speak to ...?
It's Adriana Araujo.
Tell her/him that I call back tomorrow.
