Oh, it's not Jack Dorsey with his Bin Laden beard...

...you know... I once met a man at... well, who cares. During an emotional moment he explained how he grew his beard. His brother didn't want to go to war (Israeli) but he said to him: "If you run away like a coward, I'll never speak to you again." His brother was killed.

Since that day... he never shaved. Grew a beard. Probably was psychological from the guilt. He felt he was responsible. And was hiding from himself. (Later after the confession, he shaved).

Think maybe Jack Dorsey did that?
