I'm thinking of throwing out presents I purposely break.
What is your point of purposely breaking the presents someone got you?
So that I can get get better presents.
Presents that you don't want seem to be useless, but you want to still keep them in one piece. If they were given to you with love then it is terrible to break them and just get a new one of something else. That is not how life works, you will learn the hard way if you continue to do this in life.
But I deserve better presents.
It is not good up to break the gifts you receive on purpose just to get better presents. You are better off maybe just telling the person you do not like them or just saying thank you for the gift and moving on. People might stop giving you gifts if you don't appreciate them.
