How did Harold come to know that his father was a boxer?
Every son believes his father to be the best and ideal man in the world; and every father wants to give his son the best he can. Mr. Bramble wanted to give the best to his son too. He hid the truth about his profession that he was a professional heavy weight boxer for the fear that it would cause much embarrassment to his little one and that his academics might be affected. However, when Bill declared to Jerry Fisher that he will not fight at the National Sporting Club against Jimmy Murphy, Jerry in anger said all explicitly in front of Harold. He told Harold, “Tommy, you think your pa’s a commercial. He ain’t. He’s a fighting-man, doing his eight-stone-four ringside, and known to all the heads as ‘Young Porky’.”
Everybody was dumb struck at the words spilled by Fisher, and even when he was expecting a reaction from Harold, the boy instead was happy to know it all and annoyed that why it all was kept from him. Sometimes human mind fears more than necessary and what he is running away from is actually what is good for him/her.
