this morning, i was a little busy to work.

there were a lot of things i had to do and there were so many calls from economists i had to connect them to my boss.

at lunch time, one of ERI members taken me out to lunch, we went to a Japanese restaurant and had lunch.

he told me about his study on North Korea, it was very interesting.

while having lunch, he asked me when i think the unification of South and North Korea will happen. but i couldn't say certainly, it was because i hadn't been thinking about the unification significantly, so i just told him "maybe after about six years?"
