To give some examples, just as examples:
I am sorry to say, while I am reading Finnish quite ok by now, my speaking skills are very low. The first "teacher" reacted to that fact in a way, I can only call highly passive-aggressive. I sat beside her, I am pretty sure that she noticed that after an hour or so. When she asked the group something, like "what is the largest animal in your home country", she would smile and turn... to my side. The smile died on her face, and she would turn to someone else quite demonstratively. I was just a tiny bit crushed, I have to admit it. I figured, you get what you pay for, kielikahvila is free, so I am not complaining, and I just go look for another place.
The second place there were a couple employees from the library, and a couple volunteers. The first time I was alone with them, so I got a lot of "talk time" (or "stumble time" maybe

The third place I was the only female with about 10 refugees. It is nice that they can, and want to learn the language but honestly for me it is too much to deal with Finnish, and a couple refugees trying to flirt with me. Of course, I ignore that, but I am also a bit peculiar about feeling safe. Seeing that I have been learning Arabic in the past, and have been reading a LOT, I like to think that I am not your average racist person. But I am absolutely NOT willing to risk anything in that regard.
I begin to wonder whether kielikahvila is at all worth it. It is free, and I feel bad for seemingly complaining about it. But I just do not work like that. Does anyone here have good experiences that they could share, maybe including which library's kielikahvila in the wider Helsinki area is worth attending? I do not need help learning words by going through word lists, but actually speaking.
