Children are verbally represented through the use of mental and material processes as somebody who tells about their hope, obsession, and aspirations in the future, and their naive imaginations of how an adult life is In relation to the product advertised the representation signifies that unlike other providers, using 3 Indie+ is very easy; it is not as hard as to live as adults.
