Halloween is the one day of the year that you are allowed to be someone that you're not. Or maybe it's the one day of the year when you are allowed to be yourself without others judging you. Either way, it's a great excuse for a party.
"Most people are other people. Their thoughts are someone else's opinions, their lives a mimicry, their passions a quotation." _Oscar Wilde, De Profundis, 1905
"Man is least himself when he talks in his own person. Give him a mask, and he will tell you the truth." _Oscar Wilde
But my favourite of all.
"Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." _Dr. Seuss
