"Το αγόρι δεν είναι υπεύθυνο."

the boy is not in charge is a correct answer, but marked as wrong

I heard this a lot growing up.

What senses of "responsible" does υπεύθυνος cover? In control? Behaves with awareness of responsibilities? Can be blamed for something?

[troll1995]

It can be used with both meanings ;)

Why is "liable" (for υπεύθυνο) wrong?
