They are contrary but are considered a clan and often spotted not much without each other. Interestingly this metaphor applies to human nature too. Human nature is rather very bewildering when analyzed with pessimism. Look at it with optimistic glasses and you'll find them relatively frank and apprehensible. No one is perfect and yes I have learnt it much.
I love analyzing people around me and used to have the habit of categorizing people as either bad or good :P. Yes, I know, whats on your mind now. But I am no longer the same. I am a bit matured now, when it comes to human psychology :). Bliss! Nevertheless perfect too. Analyzing people is pretty much a great experience. You get to know the constructive and destructive qualities. I have known people who love to put up a notorious cloak and talk about their mischief, yet strange but true, they'll be the first to help out a person in trouble, with a clean heart lacking any hidden intentions. Then again we have the so called "goody-goody" clan who never wait to think about ways to project their virtues and yet don't miss an opportunity to bad mouth others to depict their superiority over the rest. These superficial characters are hard to decipher but once you get to taste their medicine you will never fall for their ill plots. You can never feel aura with these people, instead there will alwyas be an air of hostility haunting you when you are around them. Don't be dejected, its not just you or me who have seen people of this sort, instead they exist everywhere. Whats life without a pinch of salt? Learn to handle them tactfully with a humorous attitude. Let them know not to take you for granted.
Hopefully there exist openhearted people too who have still kept humanity alive in our community. Support them and make them feel great for the virtues they hold. Yet again people are not perfect. These cherubs may come with their share of not so appreciable qualities. But still it can be assured that such characteristics will never be a threat to the well-being of others. Though imperfect they will always lend a helping hand when you so much look forward to it. Unlike the so called "goody-goody" one's who get lost somewhere when people look forward for help.
Learn to have an optimistic look. Life is not to make use of others. It is to understand and be supportive to others. There may be a joy of pride in pointing-fingers at others, but it deprives you of the self respect that is very much important for pride. Take people as they are. Don't trust anyone blindly with the way they project themselves, a good mould need not always have a safe shadow. Adding to this, a so called bad egg need not have skeleton in the closet. Good is not really good and bad is not totally bad. Trust the true sense of a person. It is hard to uncover, but once discovered will give you an eternal bliss irrespective of what the discovery was. Trust none blindly and don't judge a person by how they behave with you during the rosy days. This will give you a great outlook on the people around you and save you from falling prey to the plots of evil attitude. Everything is just black and white!
