Just William (version 2) by Richmal Crompton (1890 - 1969)

Just William is the first book of hilarious short stories about 11-year-old William Brown -- eternally scruffy and frowning. William's family, his elder sister Ethel and brother Robert, placid mother and stern father, and never-ending supply of elderly aunts, cannot understand him. William just likes DOING things, that's all! It's not his fault he likes DOING things, is it? (Summary by Kara and Wikipedia)
