Hi please rate and correct my essay. Thanks in advance
Many people really like their childhood time, and there are absolute times in their life in which they wish to return to their childhood. The reason is that may be childhood is the happiest time in one’s life, and that’s why people wish to experience thaose day’s joy and happiness again.
To begin with, children are not aware of the main difficulties and problems that may occure during the life time. they can not see the fact of life with an open mind, and they just consider the whole world the small and happy life they are experiencing. On the other hand, adults had experienced different situations in which they have encountered essential problems, and they are aware of some obstacles in the path to their goals and aims. Children, even if they live in poor families, are not aware of the essense of poverty, because they don’t have clear ideas towards power and weakness, and even the role of money in life. These are the factors that make life joyful and happy for them, even if they don’t live in luxury.
Another permanent factor that can be taken into account, is that they don’t have to shoulder the burden of life. They are not obliged to take critical responsibilties. They are not responsible for the famili’es expenditures, like what the father of the family is responsible for; they are not the main factor in the nurture of the kids in the family, like what is the role of the mother of the family. Considering that these are the responsibilites that may acquire much of time and energy of a person, a child is free of them, and has enough time to envision life’s positive aspects and beauty. In other words, a child is free enough to see the world a place to enjoy living in.
Last but not least, as the people grow up, the loose their energy and power and are unable to do enjoyable affairs that affect their life to be happier. This significant feature in children, being more energetic, helps them to use their strength and energy to make their life happier and more enjoyable.
All in all, I think childhood is the happiest time of a person’s life. Children are more energetic and are more free than adults to use their time in a happier way. Also, they are not knowledged about the main difiiculties in life and consider the life a more easy procedure.
