Were the only alive one but really flaring and following a fast medical evacuation in my country in AMERICA, and 13 days of unemployment which I had remained and my reveille J had already a part of my body brulée and paralized with left hand and really I had lost all my memory but God thank you this grace day has L evolution of medicine and of the réaducations which I underwent I found myself a little but J always have a part of my body flaring.

是唯一还活著，但真正燃烧和下面的一个快速医疗后送我国在美国， 13天的失业问题，我一直和我起床生已经成为我身体的一部分brulée和paralized与左手实在我失去了我所有的记忆，但是上帝的恩典感谢你这一天L演变医药和réaducations我经历了我发现自己一点，但总是有J的一部分，我的身体燃烧。

The split between the two groups can hardly be papered over.
