"He was too busy to be scared."

Translation: Era troppo impegnato ad avere paura.

[aldemar1993]

Why is "indaffarato" not acceptable? I thought it meant somebody with a lot of things to do, i.e. busy.

[ilvivente]

lui era troppo occupato per essere spaventato

Would "Era troppo impegnato per avere paura" also be correct? What's the difference between "per" and "ad" here?

[ilpardo]

"Era troppo impegnato per avere paura" is right, while the proposed translation is wrong, meaning "He was too busy being scared."
