What are some of the qualities of a good parent? Use specific details and examples to explain your answer.
Children gain the most basic characteristics, which effect their entire life, from their parents. Most of our beliefs, fears, strong and weak sides, etc. come from the attitudes that our parents show us. I try to briefly detail three qualities.
Parents must be honest and keep their promise in life, not just to children, first of all. This feature makes children be respectful to and feel confidence in parents.
Secondly, parents must spend time with children. Children are our most valuable things in our life. At least I thought like that. Spending time with children creates invisable bonds between children and parents. These bonds keep children away from the bad friends and habits.
Lastly, I think the most important one is that parents let children make mistakes and take responsibility under control. By doing this, children gain the ability to separate things which are useful and good in their life.
