The good, the bad, and the ugly. After Chulmoon wrote me about the traffic signals in his town and taught me signal is 신호등, I wrote back 5 whole sentences about traffic signals. I was so proud of myself. I submitted it for writing correction.
The good news is I met my quota of 5 mistakes a day, a goal I decided on after hearing Benny Lewis talk about his goal of making 500 mistakes a day. It gives me food for thought. I will study and learn from this.
