Dear. Mr. President.
South Korea is in deep sorrow with the accident of Sewol ferry. It's been about a week since the accident first happened. But the families still await the bodies to be retrieved. Several funerals were held, but more than 100 people are still missing. We do not know, or can predict when the families will be able to get their children back (dead or alive)
At the same time, we are aware there's a plan for a meeting in Korea on 4/25 for discussing North Korea’s nuclear threat and implementation of a bilateral free trade pact.
This is not an appropriate time to discuss any kind of political issue and it's highly likely there will be more funerals on that date. You can't visit your friend holding funeral for their kids to discuss work. Korea needs time to mourn right now.
