OE
The sentence states that the man’s personality is pleasing—so pleasing that “it’s hard to be bothered by” something in his past. The first word should match pleasing, and the second should be something negative that others might overlook. “Sanguine” means cheerful and optimistic. Note that “high-handed” might sound positive, but actually means tactlessly overbearing. “Evanescent” (fading quickly, short-lived) is inappropriate to describe a personality. “Peccadilloes” are minor faults or sins—small enough that they might be overlooked if the person has other virtues. “Incendiaries” can mean either bombs or a person who stirs up conflict; the former definition is too strong for the blank, and the latter does not fit the meaning of the sentence. “Achievements” has a positive connotation, while the second blank should convey a negative connotation.
