"what has the matrix got to do with halloween? It's not scary and like an uneducated dwarf - it's not big or clever!!!"
what the hell "is" halloween? A time of the year when people dress up in costumes, usually as characters they like. There aren't any "rules" for halloween, I could see your questioning if I dressed up as neo for christmas, but guess what it's not christmas. The matrix has nothing to do with halloween if that answers your question, but dressing up in a costume from the matrix has everything to do with halloween

It also was never meant to be scary, though some took it that way, as many people that seemingly "don't get out much" mistook me for a vampire, either way my uneducated unclever costume won me 100 bucks in prize money (which sadly is only half of what I paid for it lol) but the bigger point is I had a blast and although pretty much everone loved my costume the ones that didn't I don't give 2 pieces about.
