Father & Son bonding

Royston will always sit besides daddy every morning watching how daddy feed the fishes and drink coffee. He will normally play the coffee stirrer after daddy finish drinking the coffee. When Charlton want to join the fun, Royston will beat his hands to shun him away. We are amused by Royston's actions, is it he did not like to be disturbed in his bonding with daddy ? Mummy thought that it is better to be careful of Royston's quiet character. It looks like some sort of selfishness, dislikes sharing or self-centerness. We must enforce good character building for them.
