Taking on seven years

Recently it dawned upon me that no matter how well you believe you know someone, you don't. It's understandable that it may take years to decipher someone, their characteristics and behaviour, but apparently not even close to a decade is enough. With a newly blossomed friendship it is presumed each day is bound to be a new learning experience about one another, but one would think that after years of spending almost all 356 days together, that they would have validation to judge someone. After considering someone as close as family and sharing every possible dark secret, isn't it polite to expect to be given a glimpse of someones's true side. It's tiring spending nights awake questioning where along the line a mistake was made, where on earth I stumbled upon the idea that I knew you. I guess sincerity is close to extinct in this town, so gather your defence and armour up.
