childhood

Childhood is the age span ranging from birth to adolescence.[1] In developmental psychology, childhood is divided up into the developmental stages of toddlerhood (learning to walk), early childhood (play age), middle childhood (school age), and adolescence (post-puberty).
Age ranges of childhood
The term childhood is non-specific and can imply a varying range of years in human development. Developmentally, it refers to the period between infancy and adulthood. In common terms, childhood is considered to start from birth. Some consider that childhood, as a concept of play and innocence, ends at adolescence. In many countries, there is an age of majority when childhood officially ends and a person legally becomes an adult. The age ranges anywhere from 13 to 21, with 18 being the most common.
Developmental stages of childhood
Early childhood
Early childhood follows the infancy stage, and begins with toddlerhood when the child begins speaking or taking steps independently. While toddlerhood ends around age three when the child becomes less dependent on parental assistance for basic needs, early childhood continues approximately through years seven or eight. According to the National Association for the Education of Young Children, early childhood spans the human life from birth to age eight.
Middle childhood
Main articles: Child and Preadolescence
Middle childhood begins at around age seven or eight, approximating primary school age and ends around puberty, the beginning of adolescence.
 

friendship

                                                                                                                                                                                         In a comparison of personal relationships, friendship is considered to be closer than association, although there is a range of degrees of intimacy in both friendships and associations. Friendship and association can be thought of as spanning across the same continuum. The study of friendship is included in the fields of sociology, social psychology, anthropology, philosophy, and zoology. Various academic theories of friendship have been proposed, among which are social exchange theory, equity theory, relational dialectics, and attachment styles.
Value that is found in friendships is often the result of a friend demonstrating the following on a consistent basis:
  • The tendency to desire what is best for the other
  • Sympathy and empathy
  • Honesty, perhaps in situations where it may be difficult for others to speak the truth, especially in terms of pointing out the perceived faults of one's counterpart
  • Mutual understanding and compassion
  • Trust in one another (able to express feelings - including in relation to the other's actions - without the fear of being judged); able to go to each other for emotional support
  • Positive reciprocity - a relationship is based on equal give and take between the two parties

Flower




A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. The process begins with pollination, is followed by fertilization, leading to the formation and dispersal of the seeds. For the higher plants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across the landscape. The grouping of flowers on a plant is called the inflorescence.
In addition to serving as the reproductive organs of flowering plants, flowers have long been admired and used by humans, mainly to beautify their environment but also as a source of food.
