 Doodling and scribbling are most often associated with young children and toddlers, because their lack of hand–eye coordination and lower mental development often make it very difficult for any young child to keep their coloring attempts within the line art of the subject.Despite this, it is not uncommon to see such behavior with adults, in which case it is generally done jovially, out of boredom.Typical examples of doodling are found in school notebooks, often in the margins, drawn by students daydreaming or losing interest during class.
