Because it requires chemistry between two people for this to happen.

No body to talk to in here

I agree with @Tiger, but also some people just don't want to talk and would rather pay a teacher or learn some other way.

Becouse most of person want to speak only no one want to listen to others so someone who interested to join us we reject them

I dont know, but it happens to me.

we can chat if you want! 👌🏽
