The process is quite fun, working with Peam and Fu on this subject really make research much more fun. Maybe that is what they called "atmosphere of research". However, if a proof does not come out, the world much be worse.

Just talk with Ai kong (burin) about staying at his apartment, my dear fat ขี้งอน old friend. I will stay with him on sat. 2/9 to wed. 6/9. Ai Kong, of course, request a sweet from sendai.
