proverb

• a bad tree does not yield a good apple-a bad parent does not raise good child
• a friend in need is a friend indeed-someone who helps you when you are in trouble is a real friend
• a friend's eye is a good mirror-a real friend will tell you the truth
• any time means no time-if the date of an event remains vague, it will never happen
• all things are difficult before they are easy-with practice things become easier
