is "sorry" enough?  

well, if that happend to me, i'll ask him to be responsible for things that he have done. I trust him by lending him my motor drill, and he shouldn't burnt the motor after such generousity that i've gave him.
I like to be frankly open to others, even if it broke his/her heart, still im not the one in the wrong side. I ask his responsibility is a very reasonable thing since i can choose. To choose just keep silent and grumbling within my self, or speak up and tell him how he has dissapointed me with things that he've done, and ask him how he would responsible for his ask. If he can't afford it, then just ask him to pay with something else, such as cleaning my front garden, or washing my dishes for a week / month ...

Yes it is enough. But sometimes we need some times to heal the hurt feeling we made.

I'd get furious, too. But, like you, I think I wouldn't be able to confront him. It's just hard to blurt out and confront a neigbor straightforward and say he should pay for it. I think the neighbor himself should take the initiative to replace it even if you do not say so. Doing so would back up his sincerity of being sorry.

No sorry is not enough. He should have offered to pay for it. And if he is the kind of person who wouldn't even offer to pay for it, then you should not need to feel bad asking him to.
Personally I don't lend stuff to people for this exact reason. And if I do, it's to a close friend, and something not terribly important, like a book.
If you feel guilty about not lending people things, try not to let them know what exactly you have.

UGGHH! THAT angers me..if it was me,i would have said..i understand your sorry..but that was brand new..could you please replace it? or something like that..Noo sorry was not enough in this case..if it was like a screwdriver..or hammer..ok..theer pretty cheap./lol..but if it was me..no matter what i would have broke i would have repaid for got another,,and thats what they should have done..Also..if you just bought this..is shoudl have a warranty..u should take it back and see about getting another..

That's terrible, I will tell him Im going to buy a new one and ask him to pay at least 50%, that's it. If I am in a bad mood I might even ask him for a replacement.

I'd ask him to replace it. It doesn't need to be an angry confrontation. Just explain to him that it's new and you'd never even used it.

Just a side question though... did the drill come with a warranty? There's a chance the store might replace it.

you kept the reciet right? just return it and get a new one, at least now you know it was a piece of crap and wasn't worth the money you paid for it...just go get a new one that works more than one time.

no sorry is not enough he should have offerd to pay for a new one

u have to be carefull about ur things and i think u shud ask him to pay but be nice n obviously sorry isnt enough for this kind of mistakes
