unused

I have two unused vouchers for a free meal.

I am unused to the dark nights of the countryside.

Oh shut up, Wally, Candy was thinking, although she understood why he couldn't stop babbling. He was unused to an environment he couldn't instantly brighten; he was unused to a place so despairing that it insisted on silence. He was unused to absorbing a shock, to simply taking it in. Wally's talk-a-mile style was a good-hearted effort; he believed in improving the world – he had to fix everything, to make everything better.
