what should we talk about?

hi everyone!
Im a new one to italki.

I am a new person on italki

In the pass, i used other making friend apps to look for lang. partenr.

In the past, I used other friend making apps ("social networking" apps) to look for language partners.

But i think its not a good way to look for lang. partner.

But I think they were not successful in looking for a langauge partner.

But thanks god, let me know a good guy, he told me about italki, i tried to use it to find lang. partner, its better than before.

But thanks to God, I was lucky enough to know a person who told me about italki. I tried using it to find language partners and it's better than before.

And now I have had a few language partners, we can talk on Skype.

But the problem is we don't know what should we talk about everytime.....and I can write, but listening and speaking are thus poor....so can u you give me some advices on how to talk with language partners? Thanks a lot!
