I guess that on this site there are many people who are very busy with work and family, but they also study languages and want to have a language partner. On the other hand, circumstances can change very often and they need to cancel a language exchange meeting, which can be unpleasant for a language partner.
What is your opinion about the problem?
People ask for exchange then disappears.
Probably, many partners prefer text chat only and avoid real conversations.
It's so hard to find a serious partner here.
A Teacher (professional or community tutor) is better for me.
