Translation of conical in German

My mom and dad used to speak English when they wanted to say something I shouldn't understand. In this way I have learned English. I did not tell them till late, but I did understand every word they said.
I have always met nice people so far, and I have never had a strange friends request. So far I only had problems with my grammar in various foreign languages that I am trying to acquire.
Thank you for your answer, my English is not very good, but it should be fun to learn together, don't you think? Generally, studying alone is no fun at all. So how do we proceed? How's it going?
