^That doesn’t sound very hard to do.
5 years is 33% of your lifetime.
So? What does that have to do with it? Spending the rest of his teenage life not watching three specific terrible films doesn’t exactly sound like a heavy chore. I probably won’t watch the PT again for even more time than that.
(I would also assume that “watching the PT” refers to actually sitting down in front of a screen and purposefully watching the entirety of the film; not just watching a 2 min. YouTube clip to remember something, etc.)
