Something about life I think everyone's life is a actual movie, our eyes are a digital videos camera, our memory is a MMC card, and the brain just like a film cutter,which is sensible to cut happy memories into albums (according to different stages). They alternately emerged in the brain's exhibition hall to make us keep delighted mood. Concerning about the sad part, it is set with password, only when the new sadness appears, it will automatically eliminate password and to be recorded. Day after day, year after year, we accumulated a lot of materials, when we close the eyes quietly to recall of them, we'll discovered our life is funny. The grammar may not be correct, thanks for correcting them. :)
