1) The photo of Tony Bloncourt seems quite well preserved, and for whatever reason his style seems pretty modern. It somehow creates a bit of cognitive dissonance or something; how could he have been killed by Nazis, he looks like the subject of a modern drivers license photo.
2) It is interesting that, despite being so awful, the Nazis let people write these last letters. I wonder how this tiny bit of humanity survived.
3) I wonder, is the line
> Today, I will have lived.
An expression, part of a well known poem, or something like that, in French? As the article notes
> This turn of phrase, so simple grammatically speaking, is deceptively philosophical because it captures the interval that separates the writer from the reader, the one who will have lived from the one who lives on.
It is a remarkable bit of grammatical sleight of hand to somehow pack so much this much reflection on mortality and life into, basically, a choice of tenses.
