Report Why someone wouldn't want to teach a language to a friend? in Language Learning Posted March 21, 2016 I don't understand why a friend would not teach their friends. I'm thinking it could be because of the level of friendship. If he is your best friend, I would doubt if he would not teach you the language. Teaching a new language is hard so that could be the reason why. I'm sorry for saying this but that's how I really feel. I know you feel bad and that's okay because I would feel bad too if that happened to me.
