The Difference between Since and Until When I chat with a new friend in English, I made a laughable mistake which I can't stop laughing. I wanted to tell him I didn' t learn English and read English book after graduating from secondary school. Then I typed that it's three years since I communicated with others in English. Then I felt something wrong. I found a dictionary and hoped to find out how to express it. Finally I realized that the sentence ought to be I didn' t chat with others in English until I talk with you. Is the meaning right?
