I'm doing very well.

Hi, how are you?

so ..we can talking now ?

okey ..thank u -.°

hi and welcome to interpals ;)
we can be friend ?

Yes! That's right! As further information, "desu" is used when you talk with older people or people not so close to you. So it's better and natural to use "dayo" instead of "desu" when you talk with your friends;)

Hello! How are you?
Thanks! Yes of course;)

I want to get to know you.
