Parents wont let me celebrate Christmas

[Mister Agenda]

I'm not much for gifts, but if that's the main concern: pretend to be religious and wait until you're not dependent on them to tell them that the main lesson you learned from their threats was how to be a more convincing liar because when they had a chance to respect your honesty they threw a little tantrum instead. For extra points, you can pretend to be so religious that they wish you were still an atheist.
