How to convince parents getting you Get Together for Christmas?

Hmm I think I mostly just asked my parents (dad would say no or pitch in if I had half the money or something though, or if it interfered with my studies he could take it away until I did my homework lol , my brother would help me get games sometimes because our parents had us do a contract if we borrowed money for something from each other ... he owed me a lot of money) though I was the weirdo in school that would pick up loose change on the ground... surprising how much you can pick up lol.
