What techniques and ideas make The Secret Diary of Adrian Mole aged 13 and 3/4 interesting?
Above all, what makes this novel so interesting is the way in which the diary format allows the author to capture perfectly the angst of growing up as a teenager. One of the central ideas behind this work is the way in which we come to know both the character of Adrian and the characters of those around him. This makes for an absolutely hilarious read as Adrian, being only a thirteen-year-old boy, does not really understand so much of what is going on around him and we as readers are left with the hilarious situation of realising what is going on just as Adrian continues to naively ignore the truth that is in front of his eyes.
An excellent example of this is the way that Adrian sees the affair between his mother and Mr. Lucas, their neighbour, as being just Mr. Lucas showing kindness and being "neighbourly." He is blind to the true nature of their friendship, just as in the same way he doesn't really understand the arguments that go on between his parents. He shows himself to be a thoroughly unreliable narrator, and as a result this helps us as an audience become endeared to his quirky perspective on life.
