1. Good Friday: Aquaman
For those who commemorate it, Good Friday is an incredible relief at the end of a long period of sacrificing thingsand, in many versions of the practice, its also the last Friday in that period of the calendar in which its participants arent allowed to eat meat. Thus, if you are a participant in Good Friday, you probably have been subsisting on fish for weeks, and this would be the last day. Imagine, then, if Aquaman were invited. To keep him happy, you wouldnt be able to have a main course that day (I dont care how polite he is about it), or worse, youd have to go all vegetarian and live without killing another animal for one night of the year. Then someone would get into an argument with Aquaman, demanding, If this is so important to you, where were you on all those other days we had to eat fish or accidentally eat dolphins? to which Aquaman would reply, I just wanted to be included for once, please leave me alone! and then after a long and heated debate, possibly including the occasional appearance of some summoned sharks, everyone would leave and go home with empty stomachs anyway, possibly stopping at Long John Silvers on the way home. Phew. So these were only 10 holidays (with some others alluded to). Its a good thing superheroes arent real. Inviting the regular people we know is tough enough as it is, am I right?
