midnight
As for Nimble , he was n't having a good time at all . `` I 'll never help at another party ! '' he promised himself . He could n't believe that midnight -- and the end of the party -- would ever come . At last , however , he took heart . For old Uncle Jerry Chuck came hurrying up and began taking hats and coats off Nimble 's antlers . And Nimble knew then that the party must be almost over .
