"The poor orphan who went on to save us all – so may I say – on behalf of wizarding kind. How grateful we are for your heroism. Should we bow now or will a curtsey do?"
-- Albus Potter (CC1.7)
After receiving the back-to-school presents from his father, Albus Potter and Harry have an argument, which turns into a blazing row. Harry is hoping to become closer to his son, but Albus feels that he needs to be grateful – and he also struggles with having a famous father.
They end by saying extremely hurtful things to each other, and Albus throws away and damages the gifts he received (CC1.7).

Àlbus throws Harry's baby blanket away, knocking over and spilling the love potion onto it - this proves to be extremely important to them both later on (CC4.6).
