There's a fine but definitive line between being a braggadocio and healthy self-promotion.
Wolfe Tone, who a few months before had patronizingly described him to Talleyrand as "a respectable old man whose patriotism has been known for thirty years," was now disgusted by the lying braggadocio with which Tandy persuaded the French authorities that he was a personage of great wealth and influence in Ireland, at whose appearance 30,000 men would rise in arms. Tandy was not, however, lacking in courage.
Polite, considerate with none of the usual brash braggadocio we're used to.
braggadocio hides an almost unbearable vulnerability the product of a fragile sensitivity crushed by centuries of oppression.
Let me regress a little bit and let you know why this little bit of braggadocio was put on paper.
