Is being a 'non-consensual' recipient of a water balloon such a horrible thing? With the proviso that you can, of course, simply skip school on that day if you do have some sensitivity to being water ballooned.
Correct me if i've misinterpreted your post etc, but are you actually saying that if people don't want to be water bombed etc they should stay home at the expense of their education (albeit one day)? Why should they have to avoid school for your pleasure? Could you not just say "hey, don't do anything to somebody who doesn't want it".
While the end of Year 12 is an important milestone and one that should absolutely be celebrated - something that is more important is respecting others (particularly their right to feel safe and secure at school) and unfortunately the reason why these days are so safeguarded now is due to attitudes and actions of those that can't do that

Yes. I'm struggling to understand why you don't agree. I don't think anybody (yourself included) would enjoy getting drenched or even having anything thrown at them unless they were OK with it.
At my previous school, they did like a massive colour bomb on the oval where all the year 12s and teachers went onto the oval and just bombed each other. All ended up with colour everywhere. The important thing here was that everybody there was willing and they had a lot of fun - great!
