With the arrival of September, the time comes for children to return to school. Seasoned veterans of the back-to-school routine already know what awaits them after the summer. For some however, the experience is completely new, while others have observed older siblings wishing they could pass through the doors of knowledge, enjoying the same experiences as brothers or sisters. When it comes to teenagers, some start with a little less motivation, and others with a little bit more enthusiasm, but they are veterans with the first day of classes, they have been doing this for at least nine years, so they know perfectly well how it works.
